Extremal Hypergraphs for Ryser's Conjecture: Connectedness of Line Graphs of Bipartite Graphs
Penny Haxell, Lothar Narins, Tibor Szabó
In this paper we consider a natural extremal graph theoretic problem of topological sort, concerning the minimization of the (topological) connectedness of the independence complex…
