On a Final Theory of Mathematics and Physics by Michael Rios

I got the ppt file to work. For extremal BHs this will work with the 28 charges and 28 magnetic monopoles in the 57.

I think this has to do with gauge theoretic aspects of the quaternions. I attached some time back a post on how quaternions naturally give rise to YM gauge fields. For the momentum p_{aa'} = О»_aО»_a' and the polarization Оµ^{aa'} we have the transversality condition p_{aa'}Оµ^{aa'} = 0. In addition there is the gauge transformation Оµ_{aa'} --- > Оµ_{aa'} + k p_{aa'}, k = constant so that p_{aa'}Оµ^{aa'} = 0 is invariant for a massless field. We can then find the gauge field according to these as

F^{ОјОЅ} = Пѓ^Ој_{aa'}Пѓ^ОЅ_{bb'}( p_{aa'}Оµ^{bb'} - p_{bb'}Оµ^{aa'})

The H^2 space constructs the gauge field and its dual to give the intersection form ∫F/\F = 8πk. Working in C^4 does not bring that structure in.

The 8-dim spacetime enters into this picture as the E8 Cartan matrix. The intersection form is an invariant with respect to that. This is wrapped up in the theory of gauge field in four dimensions. There is underlying this a four dimensions of C^4 or H^2 in complex variables, but underlying this are 8 dimensions in pairs of real variables.

The symmetry is really SO(4,2) ~ SU(2,2). The group on the left is the isometry group of AdS_5 = SO(4,2)/SO(4,1). The group on the right is the group for twistor space with PT^ = SU(2,2)/(SU(2,1)xU(1)). We may think of the quaternion form of this as a transition from C^4 to H^2 with SL(4,C) --- > SL(2,H). This has four complex dimensions, eight real dimensions. We might of course be so bold as to double down, with SU(2,2,C) so that SL(4,C) --- > SL(8,C), but with the above identification of pairs we have that this is SL(4,H) ~ SL(2,O).

The inclusions

R: SO(4,3)->SO(3,2)->SO(2,1)

C: SO(5,3)->SO(4,2)->SO(3,1)

H: SO(7,3)->SO(6,2)->SO(5,1)

Have as their middle group the isometry group for AdS_4, AdS_5 and AdS_7. These all share a certain relationship with each other. The AdS_5 gives as 10 dimensional theory for AdS_5xS^5, while the other two give 11-dimensional theory for AdS_4xS^7 and AdS_7xS^4. These last two are dual theories and these have a relationship with the 10 dimension theory in sense that SO(9) is a subset of SO(9,1).

The unification of these implies they are physically an aspect of the octonion. The groups in these inclusions SO(2,1), SO(3,1), SO(5,1) and SO(9,1), dimensions = 3, 4, 6, 10 correspond to physics in these respective dimensions, with 4 for gravity, 6 the CY manifold of compactification. This seems to hinge on the collination of the Moufang OP^2 by E6(-26) which contains SL(2,H) ~ SO(9,1).

There seem to be interesting connections here, and I have this suspicion that an aspect of this is related to the 5-dim moduli space for SU(2) or SO(4) bundles on 4-manifolds. The Lorentzian case gives the hyperbolic SO(4,2)/SO(4,1) ~ AdS_5.

More later after I try to bend some more metal on this.

What I have is a couple of questions. We have that a group G decomposes into H and K or G = HвЉ--KвЉ--M with the algebraic g = hвЉ•kвЉ•m. This Cartan decomposition for the exceptional groups E6(C) and E7(C) are H = E6 and K = SO(10)xSO(2) and H = E7 and K = E6xSO(2). We also have for G = E8(C) that H = E8 and K = E7xSU(2). These are symmetric spaces and are moduli of the form E6/SO(10)xU(1), E7/E6xU(1) and E8/E7xSU(2). The question is whether these are related to SLOCC groups, such as

G_4/H_4 = E_{7(-25)}/(E_{6(-78)}xU(1))

G_3/H_3 = E_{8(-24)}/(E_{7(-25)}xSL(2,R))

The first of these is D = 4, N = 2 SUSY and the second D = 3, N = 2 SUSY. These moduli spaces with E6 have SU(3) holonomy. For the static CY these are cases of the static Hodge diamond for K3 or T^6. These groups are then moduli for the CY compactification. There is then some relationship between moduli spaces. The question is, what is the nature of these moduli spaces?

The analysis I presented last week concerned characteristic determinant equation

-det(A - О»I) = О»^3 - Tr(A)О»^2 + Пѓ(A)О» - det(A) = x

for x the root of an equation involving the commutator of the elements z \in O and the associator. I worked this out for σ(A) = R(χ. χ') = ω[χ. iχ'] = symplectic form. This equation looks very similar to an elliptic curve. Of course this is for real eigenvalues diagonalized by F4. For the complex case we have a similar system diagonalized by E6. It then seems plausible that an analogous equation exists for E6 that is an elliptic curve. This means that our moduli space is a system of modular forms that are also an algebraic variety. This means the spaces above have to be taken with a quotient of some finite discrete group. The question I whether this makes any sense?

Some aspect of conformal completion of AdS spacetimes involves Kleinian groups, and I have an interest in the prospect this system would work. Heegner prime numbers are from the discriminant of elliptic curves, and these might give a quotient that would satisfy this requirement. I am not sure it this would work or not, but it seems plausible in some way.

So I am not completely bat shit crazy here. What you say about E6(-26) appears workable since it has F4 as the mcs, which in turn diagonalizes the J3(O) in the reals. As Einstein once said, "I need a little think." This stuff is not easy for me, particularly since I have been primarily employed in applied work.

Cheers LC

I will probably have to communicate by email, as I think this contest is ending soon.

The f4 algebra is the set of isometries of C\otimes OP^2, which is in a sense the "complexification" of the OP^2 that has F4 as its isometry group. The 78 dimensions of E6 is 52 26 so that E6 = F4x26, where the 26 are vectors corresponding to the Killing form = -26. The collineations e6 correspond to isometries of OP^2 by F4 as SO(9,1) and SO(9). The points that are collinear in OP^2 correspond in C^3 to SL(4,C). These are points collinear in C^3, This complex conformal group defines the set of lines connected to a loop. This is the standard system of two vertices and and two vertices _ and -.

This will then define collineations of points on algebraic curves in CP^3. I suspect in some way this may lead to the elliptic curve.

More later,

If we consider the Jordan-Wigner QM as diagonalized by F4, this seems to fit with the F4 scheme for the Kochen-Specker contextuality result. If we shift to E6 are we then generalizing the nature of quantum mechanics? Would the occurrence of real and imaginary eigenvalues correspond to the Bogoliubov coefficients in Hawking radiation.

I am curious about the physical implications of this.

Cheers LC

As I look at E6, this seems to be the case. F4 ~ SU(3,O) and E6 ~ SL(3,O), which implies there are now an additional set of operations. These are analogous to the case with SL(2,C) ~ SU(2)xU(1,1) or SU(2)xSL(2,R). The E6 is then SL(3,O) ~ SU(3,O)xSL(3,H). These SL(3,H) transformations are rapidities similar to boosts in relativity.

Kochen-Specker proved that the measurement of can't be described by a nonlocal hidden variable that has no dependency on the context of the measurement. The Kochen-Specker theorem depends upon 48 root vectors of the F4. These are the vertices of the 24 cell. The 24 vertices have lines that emanate from them. These are basis elements for 24 quantum states. These lines define projective rays in four dimensions. For any projective ray there are three others that are orthogonal to it. There are 36 quartets of these rays that are mutually orthogonal. However, there is only need for 9 of these, where the other 24 amount to over counting. These orthogonal conditions are a condition for vanishing commutators. There are further 18 rays that exist in two sets.

If each of these 18 in two sets is determined by a hidden variables. This means there are 9 variables set to one state, say 0 or 1, and the other 3 set to 1 or 0. Yet since each appears twice this means there is an even number of these, and 9 is and odd number. It is also the case that these 9 correspond to the vanishing of 9 commutators in the BFSS holographic theory of the string. The fibration

F4:A_4 ---> F_{52/36} ---> OP^2

concerns the "36" that are ker/im of the maps, and form a cohomology.

I think we can take this further with E7. With E6 we are moving from R to C, and we have "double downed" on the number roots. We can move to H and do this again. We now have that E7 is dim = 133. We can have the quotients E7(-7)/(F4(-4)xR^{26} ~ E7(-25)/(E6(-78)xU(1)) for 2 sets of 27 gauge potential plus a graviton. Physically this "double down" amounts to pairing up the boson field above. The gauge/gravity duality, by Dixon, Bern et al, illustrates how the graviton has the same quantum numbers as a pair of gluons in a colorless entanglement. This construction appears to suit this pretty well.

The twistor approach to this is to move from C^4 to H^4, which with twistor space CP^3 from C^4 gives us PH^3. This does contain CP^3xCP^3, which means a form of twistor theory is contained in this. Of course this may be generalized I think for supermanifolds CP{3|4} into PH^{3|4}. However, the universal bundle theorem for the G_{2,2} will involve a generalization form

G_{2,2} = SU(2,2)/(SU(2)xSU(2)

into

G_{2,2,C} = SU(2,2,C)/(SU(2,C)xSU(2,C)

or

G_{4,4} = SU(4,4)/SU(4)xSU(4).

Michael,

I might use your email from now on. i think it is on your paper. Anyway, is what I wrote 6 days ago at all right? Don't worry telling me it is all wrong. I'd rather know that I am wrong that not to know.

Cheers LC

The E6(-26) ~ SL(3, O) is primarily what I have in mind. The E6(-26) has the maximal compact subgroup (mcs) F4. This is interesting because it connects with F4 as a group of collineations of the OP^2. Since F4 gives the determinant and eigenvalues of the J3 E6(-26) the E6(-26) should then be a set of transformations that preserves these eigenvalues. The Cartan decomposition E6(-26) = F4 âŠ--R^{26} tensors the F4 with the R^{26} of the bosonic string, which in a Lorentz setting is R^{25,1} and is then a set of rapidities or boosts. The additional E6(6) ~ SL(3,O(4,4)) is the split form and this has the mcs USP(8). This unitary symplectic group is defined with N = 4

O(N) ⊂ U(N) ⊂ Sp(N) = USp(2N)

and for N = 8 we can use

USp(N) ⊂ U(N) ⊂ O(2N)

which is a form of the Bott periodicity. This is contained in the O(16) group where the algebra e8(8) = so(16)⊕128.

We then have physical states in E6(6)/USp(8) = E6(6)/Sp(4). The decomposition is to SO(9,1)xU(1) or SO(5,5)xU(1) for the noncompact E6(-16) or split form. The 45 dimensional SO(10) in its two forms are an adjoint 45 with 16 [lus 16-bar spinorz plus a U(1).

With respect to USP(8) this is embedded in U(8), or SU(8) or SU(4,4). In a supermanifold setting this would be SU(4,4|8). We then have that for SU(4,4) we can embed two copies of SU(2,2) for twistor spaces related to each other by some form of STU duality. The physical states in this decomposition will then be SU(2,2)/Sp(5) ~ SO(4,2)/SO(4,1) --- > AdS_5.

This then leads to a rather interesting question. The main competitor to string theory has been loop quantum gravity. This LQG has been falling in popularity because it does not readily lead to workable calculations. The 11-dimensional form of this AdS/CFT duality is with AdS_{11-n}xS^n, for n = 7 or 4. In the case of n = 7 we have the AdS_4 with states in 11 dimensions. This involves the quotient SO(3,2)/SO(3,1). In effect we must then have physical states that remove all the possible states one might compute from a direct quantization of gravity. We might then ponder whether the falsity of LQG is actually telling us something very deep.

Do you have references for these results? I have read the paper by Smolin. It appears that the multiplicative product of eigenvalues is the volume of this parallelpiped. The E6(-26) transformations are I presume boost-like transformations. The E6(-26) = F4âŠ--R^{26} or E6(-26) = F4âŠ--R^{25,1} appears to suggest there are diffeomorphisms of this parallelpiped from the Lorentz structure of this 26 dimensional space.

I am rather eager to learn more about this. The volume of the parallelpiped as given by the determinant, and as I indicated earlier this has some correspondence with the Morse index for SLOCC groups. The velocity map or momentum map m_x gives the Hessian

Hes|m|^2 = 2sum_i (dm_{x_i})âŠ--(dm_{x_i}) + 2sum_i |m_x| Hes m_{x_i},

where the different SLOCC's occur where the Hessian vanishes. This result that you cite for 1/8, ¼ and ½ SUSY BPS black holes sits close to this.

My general idea is that a quantum wave can exist in each of these minima in this abstract manifold, which I as yet do not quite understand, and the quantum wave can also quantum tunnel between these as well. The entanglement structure is then itself subject to quantum uncertainty.

With respect to LQG, the Fermi and Integral spacecraft data on the arrival times for EM radiation from a distant burstar found no dispersion predicted from LQG. Experimental data often speaks much louder volume than theory. Now to be fair this is a measurement over a very long baseline, and it might mean that true to quantum mechanics that the momentum is sharply peaked and this dispersion does not exist. A measurement of a small region with high momentum might come up with a different result.
