Analytic solutions of Volterra equations via semigroups
We show that solutions of Volterra integrodifferential equations are analytic provided the leading operator generates an analytic semigroup and the convolution kernel is in a space of analytic functions. Similar re...

On partial uniform boundedness of a semigroup generated by a perturbed Oseen operator in an exterior domain
uniform boundedness (partial uniform stability) of the corresponding analytic semigroup. The conditions are based on behavior of the resolvent of the generator L of the semigroup. In a particular case, they reduce to condi...

On Asymptotic Behavior of Solutions of a Perturbed Non-Steady Stokes Equation in an Exterior Domain
We treat the asymptotic behavior of strong solutions of a perturbed non-steady Stokes equation in an exterior domain. We formulate sufficient conditions for partial uniform boundedness (partial uniform stability) of the corresponding analytic

On Kovács–Newman ordered semigroups
The irreducibility of pseudovarieties of semigroups is studied using many different approaches including a notion of Kovacs-Newman semigroups. In this note, we answer a natural question, whether Kovacs-Newman semigroups can...
