Polynomial Stability of Semigroups Generated by Operator Matrices
Lassi Paunonen
In this paper we study the stability properties of strongly continuous semigroups generated by block operator matrices. We consider triangular and full operator matrices whose diag…

Robustness of strong stability of semigroups
Lassi Paunonen
In this paper we study the preservation of strong stability of strongly continuous semigroups on Hilbert spaces. In particular, we study a situation where the generator of the semi…
