Remarks on blow up time for solutions of a nonlinear diffusion systems with time dependent coefficients
Monica Marras · UNICA IRIS Institutional Research Information System (University of Cagliari) · 2011
We investigate the blow-up of the solutions to a nonlinear parabolic system with Robin boundary conditions and time dependent coefficients. We derive sufficient conditions on the nonlinearities and the initial data in order to obtain explicit lower and upper bounds for the blow up time t∗
