ASYMPTOTIC AND QUENCHING BEHAVIORS OF SEMILINEAR PARABOLIC SYSTEMS WITH SINGULAR NONLINEARITIES

摘要

In this paper, we consider a family of parabolic systems with singu-lar nonlinearities. We study the classification of global existence and quenching of solutions according to parameters and initial data. Furthermore, the rate of the convergence of the global solutions to the minimal steady state is given. Due to the lack of variational characterization of the first eigenvalue to the lin-earized elliptic problem associated with our parabolic system, some new ideas and techniques are introduced.
