摘要

We consider a generalized form of the Cahn–Hilliard equation, supplied with Neumann boundary conditions. This problem describes the growth of cancerous cells. We proved that the (biological) solution does not exist in general and it can blow up in a finite time. In such cases, we proved the global existence of a unique solution.
