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?
