Hiroyuki Nakaoka (Kagoshima University), Finite gentle repetitions of gentle
algebras and their Avella-Alaminos-Geiss invariants
We consider a repetition procedure to construct gentle algebras out of a given
gentle bound quiver. I would like to show how their Avella-Alaminos-Geiss
invariants are determined by those of the original one, and how this repetition
can be expressed by an upper-triangular matrix algebra. I will also mention
a few cases where this procedure preserves derived equivalences.
