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. :-( |

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. |

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? |

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 |
