Abstracts

Dixy Msapato (University of Leeds): Counting tau-exceptional sequences over Nakayama algebras. The notion of a tau-exceptional sequence was introduced by Buan and Marsh in 2018 as a generalisation of exceptional sequences over finite dimensional algebras. In this talk, I will introduce both these notions, and present counting results of tau-exceptional sequences over some classes of Nakayama algebras. In some of these cases we will see obtain closed formulas counting other well known combinatorial objects, and exceptional sequences over some path algebras of Dynkin quivers.
