题目：The odd-distance graph
报告摘要：
Let M be a metric space and D a subset of real numbers. By geometric graphs G(V,D) we mean graphs whose vertex sets V are subsets of M and two vertices are connected by an edge if their distance is in D. Probably the, most well-known graph in this category is the unit-distance graph (R^2 : {1}). My current favorite graph, a “close relative?” of the unit-distance graph is the odd distance graph: (R^2 : {1; 3; 5; …}). In this talk I will discuss this graph and time permitting I will survey some other geometric graphs, Orthogonal Representations, equiangular lines. I will conclude with some intriguing open problems.
