Dear Maxim Yurievich,
I would like to continue working on topic "E8 xE8' Cosmology".
Here is the first draft of the english translation of my thesis.

Dear Maxim Yurievich,
I added the points and references you recommended, as well as corrected some of the words. Nevertheless, I did not really understand the remark about quantum gravity [marked green]

Dear Valery,
My answer to your question is in the attached file:
You should mention that the advantage of heterotic string theory is that it is a FINITE theory, in which you get at least in one loop approximation FINITE and not INFINITE values, as in renormalizable theory, in which you hide infinities in a restricted set of finite physical quantities.
You should present more extensive list of possible forms of dark matter, e.g. mention gravitino or other stable SUSY candidates.
The list of references should be also extended: 7 references is too small number for your huge topic.
With the best regards
M.Yu.Khlopov

Dear Maxim Yurievich,
Did you mean that heterotic string theory is so-called "super-renormalizable"? Or does "finite" mean something else?
Here's the thitd draft.

Dear Valery,
I have no more time to work on your text.
You are admitted to exam
String theory is finite - it means that divergent term is equal to 0 in D=26 for bosonic string and in D=10 for ferminionic string. It was one of the greatest advantages of heterotic string approach.
Tomorrow at 9.00 MT you three should enter VIA and we'll play with you game of ticket's choice.
We'll be available with Prof. Semikoz after 10.00 MT to take exam
Good luck!
