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.

Computational geometry seminar
Title: Illuminating polygons using edge-aligned vertex floodlights Speaker: Carlos Alegría-Galicia, Universidad Nacional Autónoma de México (UNAM) Abstract: Consider a simple polygon P with n vertices, a set of n floodlights, and an angle alpha such that, on every vertex of P lies the apex of one floodlight, all the floodlights have aperture alpha, and at least one of the bounding rays of each floodlight is aligned with an edge of P. We study the problem of finding the minimum value of alpha required to cover P. This is a joint work with David Orden, Carlos Seara, and Jorge Urrutia.
