Linear maps on von Neumann algebras acting as Lie type derivation via local actions

open access: yesAIMS Mathematics, 2021
Let $ \aleph $ be a factor von Neumann algebra with $ dim > 1 $ that operates on a Hilbert space. Within the manuscript, we let out the characterization of Lie type derivation on factor von Neumann algebra of zero product as well as at projection ...

Holographic derivation of entanglement entropy from the anti-de Sitter space/conformal field theory correspondence. [PDF]

open access: yesPhysical Review Letters, 2006
A holographic derivation of the entanglement entropy in quantum (conformal) field theories is proposed from anti-de Sitter/conformal field theory (AdS/CFT) correspondence.

Using the Evolution Operator to Classify Evolution Algebras

open access: yesMathematical and Computational Applications, 2021
Evolution algebras are currently widely studied due to their importance not only “per se” but also for their many applications to different scientific disciplines, such as Physics or Engineering, for instance.

Posner’s Theorem and ∗-Centralizing Derivations on Prime Ideals with Applications

open access: yesMathematics, 2023
A well-known result of Posner’s second theorem states that if the commutator of each element in a prime ring and its image under a nonzero derivation are central, then the ring is commutative.

The Productivity of Lexemes of English Origin [PDF]

open access: yesPhilologia, 2022
The dynamism of a language is sustained by the flexible and receptive character at the lexico-semantic level. An important contribution to the development and enrichment of the current vocabulary is made not only by the lexemes of English origin ...

Evidence from neglect dyslexia for morphological decomposition at the early stages of orthographic-visual analysis

open access: yesFrontiers in Human Neuroscience, 2015
This study examined whether and how the morphological structure of written words affects reading in word-based neglect dyslexia (neglexia), and what can be learned about morphological decomposition in reading from the effect of morphology on neglexia ...

Cognitive-Discursive Modeling of Language Nomination

open access: yesВестник Кемеровского государственного университета, 2022
Systemic and structural linguistics has no answer to the question of how one can make new words, as formulated by Prof. L. V. Shcherba. Its methodology strives to distance itself from the human factor and human activity. The present article introduces an

Superstability of derivations on Banach ∗-algebras

open access: yesAdvances in Difference Equations, 2017
In this paper, we show that approximate derivations on Banach ∗-algebras are exactly derivations and also show that approximate quadratic ∗-derivations on Banach ∗-algebras are exactly quadratic ∗-derivations by the fixed point theorem.
