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.

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 ...

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.

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.

FibroScan-AST (FAST) score for the non-invasive identification of patients with non-alcoholic steatohepatitis with significant activity and fibrosis: a prospective derivation and global validation study

open access: yesThe Lancet Gastroenterology and Hepatology, 2020
Summary Background The burden of non-alcoholic fatty liver disease (NAFLD) is increasing globally, and a major priority is to identify patients with non-alcoholic steatohepatitis (NASH) who are at greater risk of progression to cirrhosis, and who will be

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

Derivative measures [PDF]

open access: yesProceedings of the American Mathematical Society, 1980
A characterization of those measures which are distribution derivatives is undertaken. For functions of n variables in BVC, the derivative measures are absolutely continuous with respect to Hausdorff n − 1 n - 1 measure.

Derivators, pointed derivators and stable derivators [PDF]

open access: yesAlgebraic & Geometric Topology, 2013
We develop some aspects of the theory of derivators, pointed derivators, and stable derivators. As a main result, we show that the values of a stable derivator can be canonically endowed with the structure of a triangulated category. Moreover, the functors belonging to the stable derivator can be turned into exact functors with respect to these ...
