Diffusion on a Graph - Florida State University

Diffusion on a Graph Diffusion Due to random motion, molecules of a high concentration will tend to flow towards a region in space where the concentration is lower. Examples: A dye injected into solution spreading through a container, or heat spreading from a region of high temperature to a region of lower temperature. The Diffusion Equation x=0 x=L. Consider Diffusion in one dimension (x) over time (t) and let u(x,t) be the concentration of the substance that is diffusing. Then & . = &.. is the Diffusion equation with Diffusion coefficient D. One would also need to supply initial values for u, u(x,0)=u0(x), and boundary conditions at each boundary. The Diffusion Equation To describe Diffusion in a domain with more than one dimension, the second partial derivative operator is replaced with the Laplacian operator.

Diffusion on a Graph What if the diffusing substance moves along edges of a graph from node to node? In this case, the domain is discrete, not a continuum. Let c be the diffusion rate across the edge, then the amount of substance that moves from node j to node iover a time period dt is c",−". /#and from node ito node j is c".−", /#. So
