J. Pascal Gollin, Dominated balanced separators in wheel-induced-minor-free graphs
Room B332 IBS (기초과학연구원)The grid theorem of Robertson and Seymour can be equivalently stated using balanced separators, that are separators whose deletion leaves every component with no more than half of the vertices …

Harry Richman, Distinguishing graphs with tropical Weierstrass weights
Room B332 IBS (기초과학연구원)I will introduce a new structure on finite graphs, which takes the form of a labeling of the vertices by nonnegative integers (possibly repeated). This labeling is isomorphism invariant, and …

Stefan Weltge, The relaxation complexity of the standard simplex is logarithmic
Room B332 IBS (기초과학연구원)For a set $X$ of integer points, the relaxation complexity $\operatorname{rc}(X)$ is the smallest number of facets of any polyhedron P whose integer points are precisely those of X. In …
