A restricted model for the bounded derived category of gentle algebras (2407.13627v2)
Published 18 Jul 2024 in math.RT and math.CO
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 $d$-term silting objects for linearly oriented $A_n$, recovering the result that they are counted by the Pfaff-Fuss-Catalan numbers.
