Title: A swim with fighting fish
Abstract:
In this talk, I will propose you an excursion into the world of bijective combinatorics. This is an area of mathematics where we find a variety of discrete objects arising in other mathematical domains, and try to establish bijective links between them in order to understand better their structure and their relations. The central objects of my PhD are an exotic generalization of parallelogram polyominoes called fighting fish : I will present them to you, draw their connections with planar maps, intervals in a lattice of Dyck paths (and maybe more, if time allows), and what we can learn from that.
