Classification of second-class 10-dimensional complex filiform Leibniz algebras

This thesis is concerned on studying the classification problem of a subclass of (n + 1)-dimensional complex filiform Leibniz algebras. Leibniz algebras that are non-commutative generalizations of Lie algebras are considered. Leibniz identity and Jacobi identity are equivalent when the multiplica...

description This thesis is concerned on studying the classification problem of a subclass of (n + 1)-dimensional complex filiform Leibniz algebras. Leibniz algebras that are non-commutative generalizations of Lie algebras are considered. Leibniz identity and Jacobi identity are equivalent when the multiplication is skew-symmetric. When studying a certain class of algebras, it is important to describe at least the algebras of lower dimensions up to an isomorphism. For Leibniz algebras, di - culties arise even when considering nilpotent algebras of dimension greater than four.

The first source is a naturally graded non-Lie filiform Leibniz algebras and another one is a naturally graded filiform Lie algebras.

In particular, a method of simplification of the basis transformations of the arbi- trary filiform Leibniz algebras which were obtained from naturally graded non-Lie filiform Leibniz algebras, that allows for the problem of classification of algebras is reduced to the problem of a description of the structural constants.
