Title: Pullback attractors for non-autonomous parabolic equations involving Grushin operators Author: Cung The Anh (Hanoi National Univ., Vietnam) Abstract: Using the asymptotic a priori estimate method, we prove the existence of pullback attractors for a non-autonomous semilinear degenerate parabolic equation involving the Grushin operator in a bounded domain. We assume a polynomial type growth on the nonlinearity, and an exponential growth on the external force. The obtained results extend some existing results for non-autonomous reaction-diffusion equations. Submitted June 8, 2009. Published January 18, 2010.
