Spectral Properties of Partial *-Algebras

TLDR
In this paper, the special case of partial *-algebras of operators is examined, in order to find sufficient hints for the study of the abstract case, and the outcome consists in the selection of a class of topological GC*-alges that behave well from the spectral point of view and that allow, under certain conditions, a faithful realization as a partial O*algebra.
Abstract
We continue our study of topological partial *algebras focusing our attention to some basic spectral properties. The special case of partial *-algebras of operators is examined first, in order to find sufficient hints for the study of the abstract case. The outcome consists in the selection of a class of topological partial *-algebras (partial GC*-algebras) that behave well from the spectral point of view and that allow, under certain conditions, a faithful realization as a partial O*-algebra.

Operators in rigged Hilbert spaces: Some spectral properties

TL;DR: In this paper, a notion of resolvent set for an operator acting in a rigged Hilbert space D ⊆ H ⊂ D × is proposed, which depends on a family of intermediate locally convex spaces living between D and D ×, called interspaces.

Order bounded elements of topological *-algebras

TL;DR: Several different notions of bounded elements of a topological *-algebra have been considered in this paper, and it is proved that under certain circumstances (in particular, when $\mathfrak{A}$ possesses sufficiently many *-representations) order-boundedness is equivalent to spectral boundedness.

Partial *-algebras of closed linear operators in Hilbert space

TL;DR: In this article, a corrected version of our statements has been included in another work by one of us, and the present addition to our paper results from extensive discusions, both orally and by correspondance, with Dr0 Kiirsten, Prof. G. Lassner and Dr. F. Mathot.

The completion of a c ⁄ -algebra with a locally convex topology

TL;DR: In this article, the structure and representation theory of a GB ⁄ -algebra with respect to a locally convex topology is investigated. But it is not known whether the multiplication of A(t) may be or not be jointly continuous.
