Abstract

Let D be an open, bounded set in euclidean space Rm (m=2, 3, ...) with boundary ?D. Suppose D has temperature 0 at time t=0, while ?D is kept at temperature 1 for all t>0. We use brownian motion to obtain estimates for the solution of corresponding heat equation and to obtain results for the asymptotic behaviour of ED(t), the amount of heat in D at time t, as t?0+. For the triadic von Koch snowflake K our results imply that {Mathematical expression} for some constant c>1. © 1994 Springer-Verlag.
