Dr. Sue Sierra Collouquim hosted by Math Stats Department-FR
Dr. Sue Sierra will speak on:
The Universal Enveloping Algebra of the Virasoro Algebra is not Noetherian
The Virasoro algebra is an infinite-dimensional Lie algebra of great importance in physics and representation theory. We answer a long-standing question and show that its universal enveloping algebra is not noetherian. We do so by exhibiting a homomorphism from the positive part of the enveloping algebra to a polynomial ring over the Weyl algebra, and analyzing the image.
This is joint work with Chelsea Walton.
