Determinant of adjacency matrix
WebTHE MATRIX-TREE THEOREM. 1 The Matrix-Tree Theorem. The Matrix-Tree Theorem is a formula for the number of spanning trees of a graph in terms of the determinant of a certain matrix. We begin with the necessary graph-theoretical background. Let G be a finite graph, allowing multiple edges but not loops. (Loops could be allowed, but they … WebGram matrix. In linear algebra, the Gram matrix (or Gramian matrix, Gramian) of a set of vectors in an inner product space is the Hermitian matrix of inner products, whose entries are given by the inner product . [1] If the vectors are the columns of matrix then the Gram matrix is in the general case that the vector coordinates are complex ...

In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its … See more 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.
