Seminars in this series are for students to talk about something of  personal interest, or a professor to describe and explore their area of research.

The talks are at a very accessible level.

Free pizzas are a regular part  of this seminar series.

### Enveloping algebras of nonassociative structures

Abstract:
Nonassociative algebras are very rich in algebraic structure. They have important applications not only in many branches of mathematics but also in physics. Perhaps, a Lie algebra is the most known example of a nonassociative algebra. In the classical theory of Lie algebras, the famous Poincar\'e-Birkhoff-Witt (PBW) theorem (Poincar\'e (1900), G. D. Birkhoff (1937), Witt (1937)) establishes a fundamental connection between Lie and associative algebras by relating the universal associative enveloping algebra to any Lie algebra $L$. Since then the analogous results for other nonassociative structures such as generalized Lie algebras, Leibnitz $n$-algebras, triple systems, etc. have been discovered. This allowed to describe their representations by means of universal enveloping algebras and to make calculations in a similar way as in a ring of polynomials $F[x_1,\ldots,x_n]$. The aim of this talk is to discuss some classical as well as recent (including the speaker's) results on the universal enveloping algebras for different types of algebras.
