Title: Enumeration with Moon Polyominoes and Beyond

Abstract: A polyomino is a shape made by connecting certain numbers of equal-sized squares, each jointed together with at least one other square along an edge. A combinatorial model, the model of fillings of polyominoes, is obtained by assigning a non-negative integer to each square of the polyomino.  This model emerged from the study of maximal monotone chains in various  combinatorial structures, including permutations, words, matchings, set partitions, integer sequences, graphs, and multi-graphs. It provides a unified frame in enumerative combinatorics and allows us to apply different algebraic tools and combinatorial transformations. In this talk I will  show how to use this model to analyze some  basic combinatorial statistics.

The pre-recorded version of this talk was made available to registered participants before the workshop.
