## Summary

The Laplacian matrix is a matrix representation of a graph used in the analysis of random walks and electrical networks on graphs. It is a discrete analog of the Laplacian operator in multivariable calculus, which measures to what extent a graph differs at one vertex from its values at nearby vertices. 1 2 It is implemented in the Wolfram Language as KirchhoffMatrix. 2 The Laplacian also appears in the matrix tree theorem. 2

Summary The Laplacian matrix is a discrete analog of the Laplacian operator in multivariable calculus, which serves a similar purpose by measuring to what extent a graph differs at one vertex from its values at nearby vertices. It is used in the analysis of random walks and electrical networks on graphs, and is implemented in the Wolfram Language as KirchhoffMatrix. The Laplacian also appears in the matrix tree theorem.
