Bethe Colloquium by Catharina Stroppel

January 2018
Catharina Stroppel

The second Bethe Colloquium in 2018 is scheduled for Thursday, January 18th (4:15 pm) in Hörsaal I:

  • Catharina Stroppel (University of Bonn, Mathematical Institute)
  • Quantum cohomology of Grassmannians via R-matrices and integrable systems
  • Hörsaal I, Physikalisches Institut

Abstract: In this talk I want to give an elementary description of the quantum cohomology rings of Grassmannians. The main idea is to connect it with a concrete model of particle configurations on a circle. The model allows to describe the case of an arbitrary Grassmannian from the case of a point using certain creation operators. As a consequence we obtain a proof of an isomorphism theorem going back to Witten between these rings and certain WZNW-fusion rings. Connections to R-matrices and equivariant quantum cohomology might be mentioned.

Planck 2018

May 2018

The 21st International Conference "Planck 2018 - From the Planck Scale to the Electroweak scale" will take place from May 21st to May 25th, 2018, at Universität Bonn.

The conference is organized by the Bethe Center for Theoretical Physics (bctp) of the Universität Bonn for a network consisting of several European research groups: Bonn, CERN, Trieste, Madrid, Oxford, Padua, Paris and Warsaw.
More information as well as the registration form are available here.

There is an accompanying Bethe Forum Program in the week following the conference.
