Homomorphisms of Bunce-Deddens algebras [PDF]
Pacific Journal of Mathematics, 1992 The homomorphisms of a Bunce-Deddens algebra \(A\) are described. Necessary and sufficient conditions for an automorphism of the canonical UHF- subalgebra of \(A\) to have an extension to an automorphism of \(A\) are given.

Representations of the q-deformed algebra U'_q(so_4)
, 2001 We study the nonstandard $q$-deformation $U'_q({\rm so}_4)$ of the universal enveloping algebra $U({\rm so}_4)$ obtained by deforming the defining relations for skew-symmetric generators of $U({\rm so}_4)$.

International Journal of Mathematics and Mathematical Sciences, 1990 It is shown that a ring homomorphism on H(G), the algebra of analytic functions on a regular region G in the complex plane, is either linear or conjugate linear provided that the ring homomorphism takes the identity function into a nonconstant function.

Neutrosophic soft cubic Subalgebras of G-algebras [PDF]
Neutrosophic 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.

Journal of New Theory, 2021 In the present manuscript, we introduce the concept of a discrete dynamical system (Ⱬ,Ψ) in BCK-algebra where Ⱬ is a BCK-algebra and Ψ is a homomorphism from Ⱬ to Ⱬ and establish some of their related properties. We prove that the set of all fixed points

The Similarity Problem for Z-stable C*-algebras
, 2011 We show that the tensor product of two unital C*-algebras, one of which is nuclear and admits a unital *-homomorphism from (the building blocks of) the Jiang-Su algebra, has Kadison's similarity property.

The algebra of mode homomorphisms
Open Mathematics, 2014 Abstract Modes are idempotent and entropic algebras. While the mode structure of sets of submodes has received considerable attention in the past, this paper is devoted to the study of mode structure on sets of mode homomorphisms. Connections between the two constructions are established.

Solvability of invariant systems of differential equations on H2$\mathbb {H}^2$ and beyond
Mathematische Nachrichten, EarlyView.Abstract We show how the Fourier transform for distributional sections of vector bundles over symmetric spaces of non‐compact type G/K$G/K$ can be used for questions of solvability of systems of invariant differential equations in analogy to Hörmander's proof of the Ehrenpreis–Malgrange theorem.

2-local triple homomorphisms on von Neumann algebras and JBW$^*$-triples [PDF]
, 2014 We prove that every (not necessarily linear nor continuous) 2-local triple homomorphism from a JBW$^*$-triple into a JB$^*$-triple is linear and a triple homomorphism.

Hom-structures on semi-simple Lie algebras
Open Mathematics, 2015 A Hom-structure on a Lie algebra (g,[,]) is a linear map σ W g σ g which satisfies the Hom-Jacobi identity: [σ(x), [y,z]] + [σ(y), [z,x]] + [σ(z),[x,y]] = 0 for all x; y; z ∈ g. A Hom-structure is referred to as multiplicative if it is also a Lie algebra
