comment Action of the endomorphism monoid on an irreducible GL-module
Sorry, I made 2 mistakes. One of them is not crucial but the other seems to be so. As it written above the Lemma and its proof are wrong. :-(

comment Asymptotic growth of recurrence relation $x_n=\min\limits_{n_1+n_2=n}(a(x_{n_1}+x_{n_2})+2n_1n_2)$
I think that you can prove by induction that for any positive $\epsilon$ there exist $C_1,C_2$ s.t. $C_1 n^{log_2 a-\epsilon}<x_n<C_2 n^{max(log_2 a,2)+\epsilon}$, for sufficiently large $n$.

Did you tried to check it numerically? It will be much easier to prove such statement by induction than to come up with one.

comment Action of the endomorphism monoid on an irreducible GL-module
Am I understand correctly that: 1.$M$ is the monoid of $n \times n$ matrices. 2. $M.v=\{mv|m\in M\}$? If yes, it's look to easy. What did I miss?

comment What is the name of the following theorem: dimension of complex irreducible representation divides order of group
Thank you very much for your detailed answer. I think I like the name "Frobenius divisibility theorem". About your last comment. Do you mean the determinant described in \S 4.2 of arxiv.org/pdf/0901.0827v5.pdf? Is there a nice way to think of the factors $P_i(x)$? Thanks again
