 ">Automating the enumeration of pattern-avoiding permutations</a>\nby Chri
 stian Bean (Reykjavik University) as part of Algebraic and enumerative com
 binatorics seminar\n\n\nAbstract\nWhen a combinatorial specification is kn
 own for a combinatorial class there are well-established tools\, such as s
 ymbolic and analytic combinatorics\, that derive an enumeration\, asymptot
 ics\, and the ability to randomly generate instances of the objects. Howev
 er\, the initial step from definition to structural description is often a
 d-hoc. This is the gap combinatorial exploration attempts to fill.\n\nIn t
 his seminar\, we will focus on the TileScope algorithm\, an application of
  combinatorial exploration to permutation classes. It is capable of findin
 g a combinatorial specification for almost every permutation class that av
 oids some subset of length 4 patterns\, and many more. The enumerations of
  these classes were either unknown or were the main results of research pa
 pers\, some as recent as 2018. We will discuss the strategies required for
  these specifications.\n\nEmail organizer for Zoom link\n

 ">q-Whittaker functions\, finite fields\, and Jordan forms</a>\nby Steven 
 Karp (UQAM) as part of Algebraic and enumerative combinatorics seminar\n\n
 \nAbstract\nThe q-Whittaker symmetric function associated to an integer pa
 rtition is a q-analogue of the Schur symmetric function. We give a new for
 mula for the q-Whittaker function in terms of partial flags compatible wit
 h a nilpotent endomorphism over the finite field of size 1/q. We show that
  considering pairs of partial flags and taking Jordan forms leads to a pro
 babilistic bijection between nonnegative-integer matrices and pairs of sem
 istandard tableaux of the same shape\, which we call the q-Burge correspon
 dence. In the q -> 0 limit\, we recover a known description of the classic
 al Burge correspondence (also called column RSK). This is joint work with 
 Hugh Thomas.\n
