Diffusion-Reaction Systems in Neutron-Fission Reactors and Ecology,stions concerning the existence and stability of positive solutions remain unanswered. For example, the existence of nontrivial positive steady state solutions in the temperature dependent case (non-prompt feedback) in Section 2 is unknown.

Asymptotic behavior of solutions of semilinear heat equations on ,,,t any ..-bounded solution approaches either a single periodic solution or a set of equilibria as . → ∞. We also consider the case where the solution blows up in a finite time and prove that under certain conditions on . the blow-up set of any solution with nonconstant initial data is a finite set.

The Mathematics of Porous Medium Combustion,ution, the form of the reaction rate, which is discontinuous as a function of the dependent variable, precludes bifurcation of non-trivial steady solutions from the branch of trivial solutions. A constructive approach to the existence theory for non-trivial global solution branches is developed. The
