Analytical expansions for parabolic equations

Matthew Lorig, Stefano Pagliarani, Andrea Pascucci

Published 2013-12-11, updated 2014-11-28Version 2

We consider the Cauchy problem associated with a general parabolic partial differential equation in $d$ dimensions. We find a family of closed-form asymptotic approximations for the unique classical solution of this equation as well as rigorous short-time error estimates. Using a boot-strapping technique, we also provide convergence results for arbitrarily large time intervals.
