|Title:||Pattern avoidance for ascent sequences|
|Speaker:||Andrew Baxter, PSU|
|In this talk I will introduce ascent sequences (enumerated by the Fishburn numbers), which are connected to several combinatorial objects. Duncan and Steingrimsson initiated study of the number of ascent sequences avoiding certain subsequences, with this work continued by Mansour, Shattuck, and others. I will outline the problem, and discuss joint work with Lara Pudwell on counting ascent sequences avoiding a pair of patterns. I will close with a conjectured formula regarding the last pair of patterns to evade a proof.|
