Too late to work on your text.
The linked document doesn't permit editing.
You should attach text (in which editing is possible) to your post,
so that I can put my comments in it.
Do you plan to attend my course in 2 semester?

My comments are in the attached file.
For the moment your text is of very low value and poor content.
I can admit you to exam tomorrow, but you should struggle hard for '3-" at it.
You can improve your text and pass exam later, or improve the English version of your referat in 2 semester, so that we can simultaneouly with exam of 2 semester improve the mark for the 1 semester.

Я поняла Вас. Буду работать над текстом и сдам экзамен позже. В какие даты это возможно?

For me any time is available.
So it depends on you: we can fix the day and time of exam as soon as you reach sufficient progress in your text

Здравствуйте. Я поправила реферат, присылаю очередную версию.

У меня вопрос, если мы рассматриваем случай, когда зеркальный мир не взаимодействует с обычным на всех этапах образования вещества, но при этом зеркальный мир, по сути, отличается от обычного только наличием 4го поколения,то мы должны рассматривать аналогичный обычному барио-, лепто-, нуклеосинтез, но с добавлением 4го поколения? В таком случае я не очень понимаю замечания в главе про барио- и лептосинтез.

Dear Olga,
My comments are in the attached file. Correct decription of the case of stable 4th family implies analysis of sphaleron transitions that establish ratio of excess of baryons and leptons of 3 light families and fermions of the 4th family. It may be too complicated for you, so let us consider sequential 4th family mixed with 3 lighter mirror family and thus unstable.
You main error is that you consider BBN with 4th family independent of 3 families of ordinary matter. The correct treatment means that in BBN of mirror matter you also take into account effect of ordinary photons, neutrinos and electron-positron pairs and in the same way you should treat ALL the relativistic speecies (both mirror and ordinary) for BBN in your mirror world.
If you arrange initial conditions so that mirror matter can be dominant form of dark matter, you should describe what kind of dark matter scenario appears in this case (what is the characteristic scale of LSS in your case?).

Thank you.
Since you planned to attend my course in 2 semester, you can start to make English version of your text.
In 2 semester the work on text is in English in Education.
You put there post "Small thesis and Exam by Olga Nepochataya" with title of your small thesis and then add in replies to this post versions of text after my comments and proposed corrections
With the best regards
