Webs and Tableau Promotion


Abstract: We will start with an introduction to webs, standard Young
tableau promotion, and the relationship between web rotation and tableau
promotion. We will then discuss increasing tableaux---a K-theoretic
analogue of SYT---and K-promotion. A big open question in this area
deals with the order of K-promotion on increasing tableaux. We will talk
about results in the 3-row case (in joint work with O. Pechenik) as
well as current efforts to relate this problem to web promotion (joint
with O. Pechenik, J. Striker, and J. Tymoczko).
