GLOBAL STABILIZATION AND BOUNDARY CONTROL OF FISHER/KPP EQUATION WITH CONSTANT PARAMETERS

ABSTRACT
In this paper, we study the initial-boundary value problem of Fisher/KPP equation with constant parameters over a bounded domain with smooth, boundary. By overcoming the non-integrability of the constant coefficients, the global stability of the solution is proven, demonstrating its convergence to a steady state as time approaches infinity
