Coulomb branch

Abstract: The Coulomb branch is a symplectic singularity that appears in the physics study of gauge theories (more precisely in 3d N=4 supersymmetric gauge theories). A recent (2013) progress in understanding the Coulomb branch was when a combinatorial formula for this singularity was introduced, named the monopole formula. This raised excitement both in physics and in mathematics.It plays an important role in a collection of physical phenomena which were hard to solve previously, and it gives a new construction of geometric singularities that opens new directions of study in representation theory. This talk will focus on the monopole formula for a quiver and will discuss the different objects and features which arise from the quiver.

Longitudinal Algebra and Geometry Open ONline Seminar (LAGOON)

Series comments: Description: Research webinar series

The LAGOON webinar series was supported as part of the International Centre for Mathematical Sciences (ICMS) and the Isaac Newton Institute for Mathematical Sciences (INI) Online Mathematical Sciences Seminars and is now sponsored by the University of Cologne and the University of Pavia. Please register here to obtain the Zoom link and password for the meetings.

LAGOON will take place online every last Wednesday of the month from 14:00-15:00 (Time Zone Berlin, Rome, Paris).

Videos of the talks can be viewed here.

Video recordings of past talks until April 2022 can still be viewed on the ICMS webpage here.
