Title: A Matching Theoretic Flat Wall Theorem

Speaker: Archontia Giannopoulou Affiliation: University of Athens Zoom: http://matroidunion.org/?page_id=2477 or please email Shayla Redlin

Abstract:

One of the key theorems in Graph Minors is the Flat Wall Theorem which asserts the existence of a large wall under certain conditions. In this talk, we discuss about graphs with perfect matchings and their relationship with digraphs. Our main focus is on a matching theoretic analogue of the Flat Wall Theorem for bipartite graphs excluding a fixed matching minor.
