Abstract
Global existence and stability results are obtained for a semifinear evolution equation of Sobolev type in a Banach space. The nonlinear term is assumed to be uniformly Lipschitz on each bounded set and to satisfy a dissipation-type inequality. Applications include various initial-boundary value problems for certain partial differential equations which have been used to model unidirectional long waves in nonlinear dispersive systems
