Diffusion equations for nonhomogeneous media. Existence of similarity solutions
Romero Romero, Francisco; Romero Romero, J.L.; Archilla, Juan F. R. (Elsevier, 1985)We study the invariance of the diffusion equation δP(x,t)/δt = (δ/δx)[D(x)δP(x,t)/δx] under continuous groups of transformations. We show the conditions which D(x) must satisfy for the existence of similarity solutions.
