A restricted model for the bounded derived category of gentle algebras

Representation Theory 2024-07-23 v2 Combinatorics

Abstract

We present a restricted model for the bounded derived category of gentle algebras that encodes the indecomposable objects and positive extensions between them. The model is then used to count the number of dd-term silting objects for linearly oriented AnA_n, recovering the result that they are counted by the Pfaff-Fuss-Catalan numbers.
