On generalized selfadjoint operators on scales of Hilbert spaces


Abstract

We consider examples of generalized selfadjoint operators that act from a positive Hilbert space to a negative space. Such operators were introduced and studied in [1]. We give examples of selfadjoint operators on the principal Hilbert space $H_ 0$ that, being considered as operators from the positive space $H_ + \subset H_ 0$ into the negative space $H_ - \supset H_ 0$, are not essentially selfadjoint in the generalized sense.

Key words: Selfadjoint operators, generalized selfadjoint operators, Hilbert space rigging.
