REPRESENTATION THEORY AND RELATED TOPICS SEMINAR
ABSTRACT: Various asymptotic
aspects of the Hook Length Formula for standard Young
tableaux have been studied recently in combinatorics and
probability. In this talk, we study the limiting
distributions that come from random variables associated
to Stanley’s q-hook-content formula for semistandard
tableaux and q-hook length formulas of Björner–Wachs
related to linear extensions of labeled forests. We show
that, while these limiting distributions are “generically”
asymptotically normal, there are uncountably many
non-normal limit laws. More precisely, we introduce and
completely describe the compact closure of the moduli
space of distributions of these statistics in several
regimes. The additional limit distributions involve
generalized uniform sum distributions which are
topologically parameterized by certain decreasing sequence
spaces with bounded 2-norm. The closure of the moduli
space of these distributions in the Lévy metric gives rise
to the moduli space of DUSTPAN distributions. As an
application, we completely classify the limiting
distributions of the size statistic on plane partitions
fitting in a box. This talk is based on joint work with
Joshua Swanson at UCSD (https://arxiv.org/abs/2010.12701).
