On the Dissolution-Growth Process of a Grain: Large Time Behavior and Special Solutions.

open access: yes, 2007
: We study here the large time behavior of the radius R(t) of a spherical grain in a dilute solution of the same substance. The evolution in time of the grain is governed by a reaction-diffusion process in the liquid phase and by a dissolution/accretion ...

Some Results On Blow Up For Semilinear Parabolic Problems

open access: yes
. We discuss on recent results concerning the asymptotics near blow-up of nonnegative solutions of u t = uxx + f(u) ; \Gamma 1 ! x ! 1; t ? 0 u(x; 0) = u 0 (x) ; \Gamma 1 ! x ! 1; where f(u) = u p with p ?
