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…

Positive forms on Banach spaces
Balint Farkas, Mate Matolcsi
The first representation theorem establishes a correspondence between positive, self-adjoint operators and closed, positive forms on Hilbert spaces. The aim of this paper is to sho…

Commutation properties of the form sum of positive, symmetric operators
Balint Farkas, Mate Matolcsi
A new construction for the form sum of positive, selfadjoint operators is given in this paper. The situation is a bit more general, because our aim is to add positive, symmetric op…
