Dear Torsten,
I found your essay intriguing in many ways, yet highly technical (unfortunately, I think beyond the scope of this contest in that respect). I was also puzzled why, when you've already assumed a model that is spatially homogeneous and isotropic, you would be interested in recovering inflation? It doesn't seem to fit.
But those two things aside, you have some very interesting results, and I see a lot of overlap with what I'm thinking about, although we're approaching the problem in some ways differently. I wonder if, when the dust settles here, you'd be interested in reading through the discussion thread I began on Ken Wharton's essay page and emailing me your thoughts on what I've put there. I think I see a possibility from your essay that would really be of mutual benefit, and I imagine you'd pick that out as well from my posts.
As I said, interesting and intriguing essay. I rated it accordingly. I look forward to hearing more from you.
Best of luck, here and always,
Daryl
