Regional blow-up of solutions to the initial boundary value problem for ut = uδ(Δu + u)
Published online by Cambridge University Press: 14 November 2011
Abstract
Non-negative solutions of the initial boundary value problem for a degenerate parabolic equation are investigated. It is shown that solutions blow up regionally in finite tine. The size of blow-up sets is determined for radially symmetric cases.
