| Oct 12, 2020 at 19:20 | comment | added | Tim Campion | Gabriel's theorem says that if $T$ is a Dynkin tree then the quiver representations of $T$ are well-behaved. I'm not sure how much is known about general trees. By the way, when you say "tree", do you just mean that the underlying undirected graph is a tree, or do you intend a condition on the orientations of the edges? | |

| Oct 12, 2020 at 17:41 | comment | added | Tim Campion | To clarify: if $T$ is a tree, a "tree in $Ch_{\mathbb Q}$" is the same thing as a functor $F(T) \to Ch_{\mathbb Q}$ where $F(T)$ is the free category on $T$ (thought of as a graph), right? In case you're not aware, the theory of quiver representations should be of interest to you. | |
