In these two talks, some results on derived representation type via topological and homological methods will be introduced: (1) Two geometric models for graded skew-gentle algebras will be introduced ...

Abstract: We revisit the representation theory in type $A$used previously to establish that the dissimilarity vectors of phylogenetic trees are points on the tropical Grassmannian variety. We use a di...

We show that a finite connected quiver Q with no oriented cycles is tame if and only if for each dimension vector d and each integral weight of Q, the moduli space M(Q.
