 Apr13 answered Different module on same set Apr13 comment Corollary to Maschke's Theorem. More general question: math.stackexchange.com/q/661519/15416 Apr13 answered Clarification: Suppose that $(v_1, \ldots ,v_n)$ is a basis of $V$ and $(w_1, \ldots ,w_n)$ is the basis of $W$ … Apr13 comment Global dimension of translation algebra @CSA Seems like quite a couple of hours by now ... :-) Apr13 answered Suppose $\dim V=n$, $\dim W =m$, and $T\in L(V,W$)… Apr12 revised Does $B = \{x-2, x(x-2), x^2(x-2)\}$ span $\{p(x)\in P_3(\mathbb{R})|p(2) = 0\}$?

Apr11 reviewed Approve Integral Domains and Unique Factorisation Domains Apr11 comment Auslander-Reiten Quiver As I already said, like this the question is too broad. Could you elaborate on how the algebras you have are given? Are they group algebras, are they given by a quiver (with or without relations)? Do you have a particular algebra in mind, that you are particularly interested in, maybe an example in a book which you don't understand? Apr11 answered Write $V=P_2(\mathbb{R})$ as a direct sum of $V=W_1\oplus W_2 \oplus W_3$ Apr11 comment Auslander-Reiten theory @DiegoHavez I can, but the comments to this question is not the right place to ask. May I suggest you ask a different question. But how to compute Auslander-Reiten quivers depends very much on the situation you are in, so it would be helpful to ask about a specific example or class of examples. Apr11 comment global dimension of bounded path algebra After you ask a question here, if you get an acceptable answer, you should "accept" the answer by clicking the check mark ✓ next to it. This scores points for you and for the person who answered your question. You can find out more about accepting answers here: How do I accept an answer?, Why should we accept answers?.
