On Homomorphisms from Cn to Cm

open access: yesRatio Mathematica, 2020
In this paper, using elementary algebra and analysis, we characterize and compute all continuous homomorphism from Cn to Cm. Also we prove that the cardinality of the set of all non-continous group homomorphism from Cn to Cm is at least the cardinality ...

A bicommutant theorem for dual Banach algebras [PDF]

open access: yes, 2010
A dual Banach algebra is a Banach algebra which is a dual space, with the multiplication being separately weak$^*$-continuous. We show that given a unital dual Banach algebra $\mc A$, we can find a reflexive Banach space $E$, and an isometric, weak ...

On approximation of homomorphisms of algebras of entire functions on Banach spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
It is known due to R. Aron, B. Cole and T. Gamelin that every complex homomorphism of the algebra of entire functions of bounded type on a Banach space $X$ can be approximated in some sense by a net of point valued homomorphism. In this paper we consider

Ternary Menger Algebras: A Generalization of Ternary Semigroups

open access: yesMathematics, 2021
Let n be a fixed natural number. Menger algebras of rank n, which was introduced by Menger, K., can be regarded as the suitable generalization of arbitrary semigroups.

Topological tensor product of bimodules, complete Hopf Algebroids and convolution algebras [PDF]

open access: yes, 2018
Given a finitely generated and projective Lie-Rinehart algebra, we show that there is a continuous homomorphism of complete commutative Hopf algebroids between the completion of the finite dual of its universal enveloping Hopf algebroid and the ...

On a conjecture concerning some automatic continuity theorems [PDF]

open access: yes, 2011
Let A and B be commutative locally convex algebras with unit. A is assumed to be a uniform topological algebra. Let h be an injective homomorphism from A to B. Under additional assumptions, we characterize the continuity of the homomorphism h^(-1) / Im(h)

Noncommutative Borsuk-Ulam-type conjectures [PDF]

open access: yes, 2015
Within the framework of free actions of compact quantum groups on unital C*-algebras, we propose two conjectures. The first one states that, if $H$ is the C*-algebra of a compact quantum group coacting freely on a unital C*-algebra $A$, then there is no ...

Noise as a Boolean algebra of $\sigma$-fields

open access: yes, 2014
A noise is a kind of homomorphism from a Boolean algebra of domains to the lattice of $\sigma$-fields. Leaving aside the homomorphism we examine its image, a Boolean algebra of $\sigma$-fields.

Neutrosophic soft cubic Subalgebras of G-algebras [PDF]

open access: yesNeutrosophic Sets and Systems, 2019
In this paper, neutrosophic soft cubic G-subalgebra is studied through P-union, Pintersection, R-union and R intersection etc. furthermore we study the notion of homomorphism on G-algebra with some results.
