Levels and sublevels of composition algebras

open access: yes, 2007
Lewis' and Leep's bounds on the level and sublevel of quaternion algebras are extended to the class of composition algebras. Some simple constructions of composition algebras of known level values are given.

MBJ-neutrosophic ideals of BCK/BCI-algebras

open access: yesOpen Mathematics, 2019
The notion of MBJ-neutrosophic ideal is introduced, and its properties are investigated. Conditions for an MBJ-neutrosophic set to be an MBJ-neutrosophic ideal are provided.

Neutrosophic N-Structures Applied to BCK/BCI-Algebras

open access: yesInformation, 2017
Neutrosophic N -structures with applications in B C K / B C I -algebras is discussed. The notions of a neutrosophic N -subalgebra and a (closed) neutrosophic N -ideal in a B C K / B C I -algebra are introduced, and several ...

Lie algebras: infinite generalizations and deformations [PDF]

open access: yes, 1990
There are many applications of Lie algebras to theoretical physics. This thesis is a study of some new mathematical structures which also are applicable to current physical ideas.

Anti implicative IF-ideals in bCK/BCI-algebras [PDF]

open access: yes, 2018
Using triangular norms, we present a new classification of fuzzy subalgebras, ideals and implicative ideals in BCK/BCI-algebras. © 2018 by Eudoxus Press, LLC.

Quiver Varieties, Category O for Rational Cherednik Algebras, and Hecke Algebras

open access: yes, 2008
We relate the representations of the rational Cherednik algebras associated with the complex reflection group S-n x (mu e)(n) to sheaves on Nakajima quiver varieties associated with extended Dynkin graphs via a Z-algebra construction.

Solvable complemented Lie algebras. [PDF]

open access: yes, 2012
In this paper a characterisation is given of solvable complemented Lie algebras. They decompose as a direct sum of abelian subalgebras and their ideals relate nicely to this decomposition.

Automorphic Lie algebras with dihedral symmetry

open access: yes, 2014
The concept of automorphic Lie algebras arises in the context of reduction groups introduced in the early 1980s in the field of integrable systems.
