Weak $A$ -frames and weak $A$ -semi-frames

Jean-Pierre Antoine, Giorgia Bellomonte, Camillo Trapani

After reviewing the interplay between frames and lower semi-frames, we introduce the notion of lower semi-frame controlled by a densely defined operator $A$ or, for short, a \emph{…

Lower semi-frames and metric operators

J-P. Antoine, R. Corso, C. Trapani

This paper deals with the possibility of transforming a weakly measurable function in a Hilbert space into a continuous frame by a metric operator, i.e., a strictly positive self-a…

Topological partial *-algebras: Basic properties and examples

J. -P. Antoine, F. Bagarello, C. Trapani

Let $A$ be a partial *-algebra endowed with a topology $τ$ that makes it into a locally convex topological vector space $A [τ]$ . Then $A$ is called a topological partial *-algebra i…
