David Munhá Correia, Rainbow matchings
Zoom ID: 869 4632 6610 (ibsdimag)I will discuss various results for rainbow matching problems. In particular, I will introduce a ‘sampling trick’ which can be used to obtain short proofs of old results as well …
Tuan Tran, Exponential decay of intersection volume with applications on list-decodability and sphere-covering bounds
Room B232 IBS (기초과학연구원)We give some natural sufficient conditions for balls in a metric space to have small intersection. Roughly speaking, this happens when the metric space is (i) expanding and (ii) well-spread, …

Ron Aharoni, A strong version of the Caccetta-Haggkvist conjecture
Zoom ID: 869 4632 6610 (ibsdimag)The Caccetta-Haggkvist conjecture, one of the best known in graph theory, is that in a digraph with

Zoom ID: 869 4632 6610 (ibsdimag)Graph Minor project by Robertson and Seymour is perhaps the deepest theory in Graph Theory. It gives a deep structural characterization of graphs without any graph

Room B232 IBS (기초과학연구원)In a reduction sequence of a graph, vertices are successively identified until the graph has one vertex. At each step, when identifying
