Diffusion Equation Solution Sequences.
Abstract
A methodology is described for deriving expansions for the solutions of parabolic differential equations which are asymptotically valid for small times. Both the Cauchy problem and the first initial-boundary value problem are studied and particular attention is given to cases in which the data is discontinuous or incompatible with the equation. The basic procedure is called DESS (Diffusion Equation Solution Sequence) method and all expansions are obtained in explicit form using certain special functions which are briefly discussed. Error estimates are rigorously stated but their proofs are not included in the present work.
