Global attractor for two-dimensional weakly damped nonlinear parametric Klein-Gordon Schrodinger system
Olivier Goubet, Marilena Poulou
Abstract
We consider a damped forced nonlinear Klein-Gordon Schr ödinger (KGS) system known as the parametric KGS system with Yukawa coupling where the space variable belongs to R 2 . We prove the existence of a global attractor in dimension 2. Moreover we prove that this global attractor is regular and has finite fractal dimension.
