The Evolution of Operator Semigroupsverse applications to many areas of mathematics and science developed rapidly. The theory was based on two main results, the wellposedness theorem and the generation theorem. By the early 1970s, analogues of these two theorems were developed for semigroups of nonlinear operators. Since then, extensi

On Strong Convergence to Ergodic Projection for Perturbed Substochastic Semigroupsgroup generated by . We show that if some remainder term . of the Dyson-Phillips expansion of . depends continuously on . in the uniform topology then . converges strongly to its ergodic projection as .. The proof relies on a “0–2” law for .-semigroups by G. Greiner. We characterize also the existen

On Robustness of Strongly Stable Semigroups with Spectrum on ,generator of the unperturbed semigroup has a finite spectral point on the imaginary axis and the resolvent operator is polynomially bounded elsewhere on the imaginary axis. As our main result we present conditions for preservation of the strong stability of the semigroup under bounded perturbations.
