ELEMENTARY SOLUTIONS OF A HOMOGENEOUS Q-SIDED CONVOLUTION EQUATION

open access: yesПроблемы анализа, 2018
Spectral synthesis on the complex plane related to solutions of some homogeneous equations of convolution type. There is a method to obtain solutions: we describe the elementary solutions set of the equation (spectral analysis) and prove the ...

Some properties of shift operators on algebras generated by $*$-polynomials

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
A $*$-polynomial is a function on a complex Banach space $X,$ which is a sum of so-called $(p,q)$-polynomials. In turn, for non-negative integers $p$ and $q,$ a $(p,q)$-polynomial is a function on $X,$ which is the restriction to the diagonal of some ...

Non-archimedean shift operators [PDF]

open access: yesP-Adic Numbers, Ultrametric Analysis, and Applications, 2010
We introduce and study non-Archimedean analogs of the operators of unilateral shift and backward shift playing crucial roles in the classical theory of nonselfadjoint operators. In particular, we find various functional models of these operators having both common and different features compared to their classical counterparts.

AdS weight shifting operators [PDF]

open access: yesJournal of High Energy Physics, 2018
AbstractWe construct a new class of differential operators that naturally act on AdS harmonic functions. These are weight shifting operators that change the spin and dimension of AdS representations. Together with CFT weight shifting operators, the new operators obey crossing equations that relate distinct representations of the conformal group.

A natural space of functions for the Ruelle operator theorem [PDF]

open access: yes, 2007
We study a new space, $R(X)$, of real-valued continuous functions on the space $X$ of sequences of zeros and ones. We show exactly when the Ruelle operator theorem holds for such functions.

On Fuzzy Soft Linear Operators in Fuzzy Soft Hilbert Spaces

open access: yesAbstract and Applied Analysis, 2020
Due to the difficulty of representing problem parameters fuzziness using the soft set theory, the fuzzy soft set is regarded to be more general and flexible than using the soft set.
