On Fuglede's conjecture and the existence of universal spectra
Bálint Farkas, Máté Matolcsi, Péter Móra
Recent methods developed by Tao \cite{tao}, Kolountzakis and Matolcsi \cite{nspec} have led to counterexamples to Fugelde's Spectral Set Conjecture in both directions. Namely, in $…

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…
