Tomography in Hilbert spaces

open access: yesJournal of Physics: Conference Series, 2007
We present a method of constructing the tomographic probability distributions describing quantum states in parallel with density operators in abstract Hilbert spaces. After the study of an infinite dimensional example, the well known Husimi-Kano quasi-distribution is reconsidered in the new setting and a new tomographic scheme based on coherent states ...

On bidual bases in the space of symmetric analytic functions on $ell_{1}$

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
We consider a special Hilbert space of symmetric analytic functions on$ell_1$ and construct a pair of bidual bases of polynomials.}{Hilbert space, symmetricanalytic functions, bidual ...

Fixed Point and Acute Point Theorems for New Mappings in a Banach Space

open access: yesJournal of Mathematics, 2019
In a Hilbert space, concepts of attractive point and acute point are studied by many researchers. Moreover, these concepts extended to Banach space. In this paper, we introduce a new class of mappings on Banach space corresponding to the class of all ...
