Pontryagin Space Structure in Reproducing Kernel Hilbert Spaces over *-semigroups
Franciszek Hugon Szafraniec, Michal Wojtylak
The geometry of spaces with indefinite inner product, known also as Krein spaces, is a basic tool for developing Operator Theory therein. In the present paper we establish a link b…
