DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WiSe/13/">Wh
 at is a Coulomb branch?</a>\nby Alex Weekes (University of British Columbi
 a) as part of What is ...? Seminar\n\n\nAbstract\nAs hinted at in their na
 me\, Coulomb branches come from physics: they are spaces which physicists 
 associate to certain quantum field theories. But it so happens that many s
 paces of mathematical interest arise as Coulomb branches\, which are espec
 ially important in representation theory and in the study of integrable sy
 stems.\nAs with many constructions in quantum field theory\, a precise mat
 hematical definition of Coulomb branches was difficult to achieve. Fortuna
 tely for us this was accomplished in recent work of Braverman\, Finkelberg
  and Nakajima (BFN)\, who provide a rigorous definition in a large family 
 of cases.\nIn this talk we will take a look at the BFN construction of Cou
 lomb branches\, making stops along the way to see some of the interesting 
 spaces that arise.\n
