Existence and nonexistence of global solutions to the Cahn-Hilliard equation with variable exponent sources

Quach V. Chuong, Le C. Nhan, Le X. Truong

Abstract:
In this article, we study the existence and nonexistence of global solutions to the Cahn-Hilliard equation with variable exponent sources and arbitrary initial energy. We also study the asymptotic behavior of weak solutions. Our results extend some recent results of Han [11] to PDEs with variable exponent sources.
