Weakly and almost weakly stable C_0-semigroups
Tanja Eisner, Balint Farkas, Rainer Nagel +1
In this paper we survey results concerning the asymptotic properties of C_0-semigroups on Banach spaces with respect to the weak operator topology. The property "no eigenvalues of…
On the weak analogue of the Trotter-Kato theorem
Tanja Eisner, Andras Sereny
In the Trotter-Kato approximation theorem for C_0-semigroups on Banach spaces, we replace the strong by the weak operator topology and discuss the validity of the relevant implicat…
Category theorems for stable semigroups
Tanja Eisner, Andras Sereny
Inspired by the classical category theorems of Halmos and Rohlin for the discrete measure preserving transformations, we prove analogous results in the abstract setting of unitary…
Category theorems for stable operators on Hilbert spaces
Tanja Eisner, Andras Sereny
We discuss the two closely related, but different concepts of weak and almost weak stability for the powers of a contraction on a separable Hilbert space. Extending Halmos' and Roh…
