Karin Baur, Bethany Marsh
We give a geometric model for a tube category in terms of homotopy classes of oriented arcs in an annulus with marked points on its boundary. In particular, we interpret the dimens…

On the complement of the dense orbit for a quiver of type $\Aa$
Karin Baur, Lutz Hille
Let $\Aa_t$ be the directed quiver of type $\Aa$ with vertices. For each dimension vector there is a dense orbit in the corresponding representation space. The principal ai…
