Linear operators form the cornerstone of analysis in Banach spaces, offering a framework in which one can rigorously study continuity, spectral properties and stability. Banach space theory, with its ...
Journal of Operator Theory, Vol. 48, No. 1 (Summer 2002), pp. 151-186 (36 pages) Motivated by recent developments in the theory of quantum groups, some classes of q-deformed operators (q-normal, ...
Abstract. In this paper, we consider three classes of bounded linear operators on a topological vector space with respect to three different topologies which are introduced by Troitsky. We obtain some ...
In the context of quantum physics, the term "duality" refers to transformations that link apparently distinct physical theories, often unveiling hidden symmetries. Some recent studies have been aimed ...
