Zilin Jiang Forbidden subgraphs and spherical two distance sets, Mo CCA20

The talk Forbidden subgraphs and spherical twodistance sets by Zilin Jiang on the Moscow Conference on Combinatorics and Applications at MIPT. Annotation: A spherical twodistance set is a set of unit vectors in ddimensional Euclidean space such that the inner products between two distinct vectors assume only two values, say α and β. In this talk, I will connect the problem of determining the maximum size of a spherical twodistance set in Rd to forbidden subgraph characterization of signed graphs with eigenvalues bounded from below.
