Let ?. and ?. denote the real vector spaces with coordinates indexed by the edges and vertices of X, respectively. Then the column space of .. is a subspace of ?., called the . of .. The orthogonal complement of this vector space is called the . of ..

Rethinking Peace and Conflict Studiess also a homomorphic image of the graph. Studying graphs that are equal to their core leads us to an interesting class of graphs first studied by Andrásfai. We finish the chapter with an exploration of the cores of vertex-transitive graphs.

Decolonizing Psychoanalytic Technique lines is determined by the angle between them. Therefore, a simplex is a set of lines in ?. such that the angle between any two distinct lines is the same. We call this a set of .. In this chapter we show how the problem of determining the maximum number of equiangular lines in ?. can be expressed in graph-theoretic terms.
