On Algebraic properties of ABO-Blood Type Inheritance Pattern
J. M. Casas, M. Ladra, B. A. Omirov +1
We generate an algebra on blood phenotypes with multiplication based on human ABO-blood type inheritance pattern. We assume that during meiosis gametes are not chosen randomly. For…
The classification of naturally graded Zinbiel algebras with characteristic sequence equal to
J. K. Adashev, M. Ladra, B. A. Omirov
This work is a continuation of the description of some classes of nilpotent Zinbiel algebras. We focus on the study of Zinbiel algebras with restrictions to gradation and character…
Non-abelian tensor product and homology of Lie Superalgebras
Xabier García-Martínez, Emzar Khmaladze, Manuel Ladra
We introduce the non-abelian tensor product of Lie superalgebras, study some of its properties including nilpotency, solvability and Engel, and we use it to describe the universal…
Universal central extensions of of small rank over associative superalgebras
Xabier García-Martínez, Manuel Ladra
We complete the solution of the problem of finding the universal central extension of the matrix superalgebras where is an associative superalgebra and…
Universal central extensions of Lie-Rinehart algebras
José Luis Castiglioni, Xabier García-Martínez, Manuel Ladra
In this paper we study the universal central extension of a Lie--Rinehart algebra and we give a description of it. Then we study the lifting of automorphisms and derivations to cen…
