Abstract: Our aim in this paper is to prove the existence to a Cahn–Hilliard equation with a proliferation term and endowed with Neumann boundary conditions. Such a model has, in particular, applications in biology. We first consider regular nonlinear term then logarithmic one. We finally give some numerical simulations which confirm the theoretical results.

Keywords: Cahn-Hilliard equation, proliferation term, regular nonlinear term, logarithmic nonlinear term, existence, simulations
