Asymptotic stability of linear differential equations in Banach spaces. (English) Zbl 0639.34050
Let A be a generator of a strongly continuous bounded semigroup T(t), \(t\geq 0\). We prove that if the intersection of the spectrum of A and the imaginary axis is at most countable and \(A^*\) has no purely imaginary eigenvalues, then the Cauchy problem for the differential equation \(\dot x(t)=Ax(t)\), \(t\geq 0\), is asymptotically stable.
