The enumeration of inversion sequences avoiding the patterns 201 and 210
Published 30 Oct 2023 in math.CO | (2310.19632v3)
Abstract: We derive the algebraic generating function for inversion sequences avoiding the patterns $201$ and $210$ by describing a set of succession rules, converting them to a system of generating function equations with one catalytic variable, and then solving the system with kernel method techniques.
