Omsk Algebraic Webinar #966 will be held on January 19

On January 19 at 7 pm Novosibirsk time (6 pm Omsk time, 3 pm Moscow time) the seminar #966 of  will take place. Marina Rasskazova (Omsk State Technical University) will present her talk â€œBinary Lie algebras and its application to the theory of Binary Lie superalgebrasâ€.

By definition an algebra $B$ is binary-Lie algebra iff any two elements $a,b\in B$ generate a Lie subalgebra. A ${\bf Z}_2-$graded algebra $B=B_0\oplus B_1$ is a binary-Lie superalgebra iff $B\times \Gamma=B_0\otimes \Gamma_0\oplus B_1\otimes \Gamma_1$ is a binary Lie algebra, where $Gamma=Gamma_0\oplus Gamma_1$ is a Grassman algebra with natural  gradation. We apply the theory of binary-Lie algebras for proving the following result.

Theorem. Let $B=B_0\oplus B_1$ be  a simple binary-Lie superalgebra finite dimensional over the field ${\bf C}$ of complex numbers. Then $B_0$ is a solvable algebra or $B$ is a Lie superalgebra.

This theorem reduced the problem (open yet!) of classification of a simple binary-Lie superalgebra finite dimensional over the field ${\bf C}$ to the case where subalgebra $B_0$ is solvable.

This talk is based on the joint paper with A.Grishkov and I.Shestakov.
