Periodic doubly degenerate parabolic equation with nonlocal terms
This paper is a remark on Gao and Wang (2007) [4]. Under some weaker conditions than PI, we establish the existence of nontrivial nonnegative periodic solutions for a doubly degenerate parabolic equation with nonlocal terms. The key is the use of De Giorgi iteration technique and the theory of Leray-Schauder degree. (C) 2010 Elsevier Ltd. All rights reserved.
