Unification modulo a partial theory of exponentiation [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2010
Modular exponentiation is a common mathematical operation in modern cryptography. This, along with modular multiplication at the base and exponent levels (to different moduli) plays an important role in a large number of key agreement protocols.

Hypercyclicity of adjoint of convex weighted shift and multiplication operators on Hilbert spaces [PDF]

open access: yesMathematics and Computational Sciences, 2021
A bounded linear operator $T$ on a Hilbert space $\mathfrak{H}$ is convex, if $$\|\mathfrak{T}^{2}v\|^2-2\|\mathfrak{T}v\|^2+\|v\|^2 \geq 0.$$ In this paper, sufficient conditions to hypercyclicity of adjoint of unilateral (bilateral) forward (backward ...

Isometric multiplication operators and weighted composition operators of BMOA

open access: yesJournal of Inequalities and Applications, 2021
Let u be an analytic function in the unit disk D $\mathbb{D}$ and φ be an analytic self-map of D $\mathbb{D}$ . We give characterizations of the symbols u and φ for which the multiplication operator M u $M_{u}$ and the weighted composition operator M u ,

Multiplication operators on weighted Bloch spaces of the first Cartan domains

open access: yesJournal of Inequalities and Applications, 2020
Let ℜ I ( m , n ) $\Re_{I}(m,n)$ be the first Cartan domain. Motivated by some results of the multiplication operators on the holomorphic function spaces on the unit ball of C n ${\mathbb {C}}^{n}$ , we study multiplication operators on weighted Bloch ...

Multiplication operators on the space of functions of bounded variation

open access: yesDemonstratio Mathematica, 2017
In this paper,we study the properties of the multiplication operator acting on the bounded variation space BV[0, 1]. In particular,we show the existence of non-null compact multiplication operators on BV[0, 1] and non-invertible Fredholm multiplication ...

Hypercyclicity of Composition Operators on Orlicz Function Spaces

open access: yesMoroccan Journal of Pure and Applied Analysis, 2020
In this paper, we discuss the hypercyclic properties of composition operators on Orlicz function spaces. We give some different conditions under which a composition operator on Orlicz spaces is hyper-cyclic or not. Similarly, multiplication operators are

Operations on Hesitant Linguistic terms sets Induced By Archimedean Triangular Norms And Conorms

open access: yesInternational Journal of Computational Intelligence Systems, 2018
The aim of the paper is to discuss some new operations on hesitant fuzzy linguistic terms sets based on Archimedean t-norm and t-conorm. The advantage is that the operations on hesitant fuzzy linguistic terms sets are closed, by studying propositions of ...

On a Sum of More Complex Product-Type Operators from Bloch-Type Spaces to the Weighted-Type Spaces

open access: yesAxioms, 2023
The aim of the present paper is to completely characterize the boundedness and compactness of a sum operator defined by some more complex products of composition, multiplication, and mth iterated radial derivative operators from Bloch-type spaces to ...

Volterra integral operators on a family of Dirichlet-Morrey spaces [PDF]

open access: yesOpuscula Mathematica, 2023
A family of Dirichlet-Morrey spaces \(\mathcal{D}_{\lambda,K}\) of functions analytic in the open unit disk \(\mathbb{D}\) are defined in this paper. We completely characterize the boundedness of the Volterra integral operators \(T_g\), \(I_g\) and the ...
