Commutative families in DIM algebra, integrable many-body systems and q, t matrix models

open access: yesJournal of High Energy Physics
We extend our consideration of commutative subalgebras (rays) in different representations of the W 1+∞ algebra to the elliptic Hall algebra (or, equivalently, to the Ding-Iohara-Miki (DIM) algebra U q , t gl ̂ ̂ 1 $$ {U}_{q,t}\left({\hat{\hat{\mathfrak ...

Hyers-Ulam-Rassias stability of Jordan homomorphisms on Banach algebras

open access: yesJournal of Inequalities and Applications, 2005
We prove that a Jordan homomorphism from a Banach algebra into a semisimple commutative Banach algebra is a ring homomorphism. Using a signum effectively, we can give a simple proof of the Hyers-Ulam-Rassias stability of a Jordan homomorphism between ...

Deformations over non-commutative base

open access: yesComptes Rendus. Mathématique
We make some remarks on deformation theory over non-commutative base. We describe the base algebra of semi-universal non-commutative deformations using vector spaces $T^1$ and $T^2$.

The Centroid of a Lie Triple Algebra

open access: yesAbstract and Applied Analysis, 2013
General results on the centroids of Lie triple algebras are developed. Centroids of the tensor product of a Lie triple algebra and a unitary commutative associative algebra are studied.

Stability of -Jordan Homomorphisms from a Normed Algebra to a Banach Algebra

open access: yesAbstract and Applied Analysis, 2013
We establish the hyperstability of -Jordan homomorphisms from a normed algebra to a Banach algebra, and also we show that an -Jordan homomorphism between two commutative Banach algebras is an -ring homomorphism.
