Some remarks on quasi-Hermitian operators
2014
A quasi-Hermitian operator is an operator that is similar to its adjoint in some sense, via a metric operator, i.e., a strictly positive self-adjoint operator.Whereas those metric operators are in general assumed to be bounded, we analyze the structure generated by unbounded metric operators in a Hilbert space. Following our previous work, we introduce several generalizations of the notion of similarity between operators. Then we explore systematically the various types of quasi-Hermitian operators, bounded or not. Finally, we discuss their application in the so-called pseudo-Hermitian quantum mechanics.

Representations of modules over a *-algebra and related seminorms
2008
Representations of a module X over a ∗-algebra A# are considered and some related seminorms are constructed and studied, with the aim of finding bounded ∗-representations of A#.
