In this paper, we consider a particular type of nonlinear McKend-rick-von Foerster equation with a diffusion term and Robin boundary condition. We prove the existence of a global solution to this equation. The steady state solutions to the equations that we consider have a very important role to play in the study of long time behavior of the solution. 'Therefore we address the issues pertaining to the existence of solution to the corresponding stage equation. Furthermore, we establish that the solution of McKend-rick-von Foerster equation with diffusion converges pointwise to the solution of its steady state equations as time tends to infinity.
