Title: Recent progress on 2-walk-regular graphs
Abstract:
In this talk I will present some recent progress on 2-walk-regular graphs.
This is based on joint work with Zhi Qiao, Jongyook Park and Shao-Fei Du.

The Geometric Graphs week (formerly Pseudo Triangulations week) brings together a group of about 20 researchers to work in cooperation on open problems brought by the organizers and the participants.
This year it is organized by the DCCG UPC Research Group.

Computational geometry seminar 19-05-2016
Speaker: Pilar Cano - Universitat Politècnica de Catalunya and Carleton University A rainbow matching in an edge colored hypergraph is a matching such that each pair of its edges have distinct colors. Brualdi, Ryser and Stein conjectured the existence of a partial n-1 Latin transversal in a Latin square n-matrix. This problem can be translated into finding a rainbow matching in a complete bipartite graph. We extend the result of Erds and Spencer on the existence of rainbow matchings in the complete bipartite graph {n,n} to complete r-partite r-uniform graphs, complete bipartite graphs with repeated edges, and d-regular bipartite graphs minus a matching. The results use the Lopsided version of the Local Lovász Lemma.

Abstract: A rainbow matching in an edge colored hypergraph is a matching such that each pair of its edges have distinct colors.
Brualdi, Ryser and Stein conjectured the existence of a partial $n-1$ Latin transversal in a Latin square $n$-matrix.
This problem can be translated into finding a rainbow matching in a complete bipartite graph. We extend the result of Erd\H{o}s and Spencer on the existence of rainbow matchings in the complete bipartite graph $K_{n,n}$ to complete $r$-partite $r$-uniform graphs, complete bipartite graphs with repeated edges, and $d$-regular bipartite graphs minus a matching. The results use the Lopsided version of the Local Lovász Lemma.
