Algebra Seminar

On the center of Lie algebras

Kamgarpour

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 \(\mathfrak{g}\).
I will then define the notion of quasi-Verma modules for the above mentioned vertex algebra, and stipulate how the Feigin-Frenkel Center should act on these modules.

We will take the speaker to lunch after the talk.
