Abstract
We consider a nonlinear parabolic system with Neumann boundary conditions which solution may blow up in finite time t*: We determine a lower bound for t* by using a Sobolev type inequality. In addition an upper bound for t* is obtained, under alternative conditions on the non linearities.Items in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
