Global existence and L ∞ estimates of solutions for a quasilinear parabolic system

Global existence and L ∞ estimates of solutions for a quasilinear parabolic system In this paper, we study the global existence, L ∞ estimates and decay estimates of solutions for the quasilinear parabolic system u t = div (|∇ u | m ∇ u ) + f ( u , v ), v t = div (|∇ v | m ∇ v ) + g ( u , v ) with zero Dirichlet boundary condition in a bounded domain Ω ⊂ R N . In particular, we find a critical value for the existence and nonexistence of global solutions to the equation u t = div (|∇ u | m ∇ u ) + λ | u | α - 1 u . http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Evolution Equations Springer Journals

Abstract

In this paper, we study the global existence, L ∞ estimates and decay estimates of solutions for the quasilinear parabolic system u t = div (|∇ u | m ∇ u ) + f ( u , v ), v t = div (|∇ v | m ∇ v ) + g ( u , v ) with zero Dirichlet boundary condition in a bounded domain Ω ⊂ R N . In particular, we find a critical value for the existence and nonexistence of global solutions to the equation u t = div (|∇ u | m ∇ u ) + λ | u | α - 1 u .
