Graph matrices
WebApr 23, 2024 · Adjacency matrices of directed graphs only cover one side of the diagonal line, since directed graphs have edges that go in only one direction. An adjacency matrix can be “weighted”, which basically means each edge has an associated value attached to it, so instead of 1s, the value is put in the respective matrix coordinate. These weights ... For a simple graph with vertex set U = {u1, …, un}, the adjacency matrix is a square n × n matrix A such that its element Aij is one when there is an edge from vertex ui to vertex uj, and zero when there is no edge. The diagonal elements of the matrix are all zero, since edges from a vertex to itself (loops) are not allowed in simple graphs. It is also sometimes useful in algebraic graph theory to replace the nonzero elements with algebraic variables. The same concept can be ext…

Webby-n Boolean adjacency matrices of two undirected graphs. If the matrix multiplication is redefined to use logical AND instead of scalar multiply, and if it uses the logical OR instead of add, then the matrix C is the sparse Boolean adjacency matrix of a graph that has an edge (i,j)if node i in A and node j in B share any neighbor in common. Webters outline the basic properties of some matrices associated with a graph. This is followed by topics in graph theory such as regular graphs and algebraic connectiv-ity.
