On the spectrum of weakly almost periodic solutions of certain abstract differential equations
In a sequentially weakly complete Banach space, if the dual operator of a linear operator A satisfies certain conditions, then the spectrum of any weakly almost periodic solution of the differential equation \(u'=Au+f\) is identical with the spectrum of f except at the origin, where f is a weakly almost periodic function.
