Long-time behavior and regularity are studied for solutions of the Stark equation It is shown that for a class of short-range potentials V(x) the gain of local smoothness and the decay as |t| Γ are close to those of the corresponding Schro dinger equation u t =i(&2+V(x)) u.

In this work, we prove the existence of global attractor for the nonlinear evolution equation
. This improves a previous result of Xie and Zhong in (J. Math. Anal. Appl. 2007; 336:54-69.) concerning the existence of global attractor in H 1 0 (X)ΓH 1 0 (X) for a similar equation. Further, the asymptotic behavior and the decay property of global solution are discussed.

We show that weak L p dissipativity implies strong L dissipativity and therefore implies the existence of global attractors for a general class of reaction diffusion systems. This generalizes the results of Alikakos and Rothe. The results on positive steady states (especially for systems of three eq
