On the center of Lie algebras

Friday 7th June, 12:05-12:55pm, Carslaw 373

Speaker:

Masoud Kamgarpour (University of Queensland)

Title:

On the center of Lie algebras

Abstract:

I will discuss the center of (the universal enveloping algebra) four different kinds of Lie algebras:

1. Harish-Chandra's description of the centre of a simple algebra $\mathfrak{g}$;
2. Kirillov-Duflo's description of the centre of an arbitrary finite dimensional algebra;
3. Center of the jet algebra $\mathfrak{g}[[t]]$ and loop algebra $\mathfrak{g}((t))$;
4. Feigin-Frenkel description of center of the vertex Lie algebra associated to $\mathfrak{g}$.
