Abstract:
This paper is devoted to the analytic semigroup approach to semilinear parabolic initial boundary value problems arising in combustion theory which obey a general Arrhenius equation and Newtonian cooling. We prove a global existence and uniqueness theorem of positive solutions by using the theory of analytic semigroups in the topology of uniform convergence. Moreover, we study the asymptotic stability of maximal and minimal positive solutions when there are multiple steady-state solutions.

Keywords: Semilinear parabolic boundary value problem, Arrhenius equation, Newtonian cooling, thermal explosion, analytic semigroup
