About this seminar

There is a session more or less every two weeks. Any volunteer is welcome to give a talk between 30 and 45 minutes. The seminary aims at creating links between the students and let them know which topic are worked on in the Turing building. The talks are thus supposed to be introductory and reasonably accessible.

Mathias Lepoutre: What reflections on embedded structures teach us about walk

Abstract: This is a part of the work I did last summer for my master internship. I will present some (hopefully) very accessible and picturesque results. Embedded structures are in bijection with various lattice walk objects, and a reflection on the former often gives rise to a non-trivial involution on the latter. We will see a few examples of this phenomenon, involving plane binary trees, Dyck paths, Schnyder woods, and plane bipolar orientations.
