DESCRIPTION:Tommaso Botta (ETZH)\nMirror symmetry for 3d N=4SUSY QFTs has 
 recently received much attention in geometry and representation theory. Th
 eories within this class give rise to interesting moduli spaces of vacua\,
  whose most relevant components are called the Higgs and Coulomb branches.
  Nakajima initiated themathematical study of Higgs branches in the 90s\; s
 ince then\, their geometry has been pivotal in diverse areas of enumerativ
 e geometry and geometric representation theory. On the other hand\, a math
 ematically precise definition of the Coulomb branch has onlyrecently been 
 proposed\, and its study has started. \n\nPhysically\, 3d mirror symmetry
 is understood as a duality for pairs of theories whose Higgs and Coulomb b
 ranches are interchanged. Mathematically\, it descends to a number of stat
 ements relating invariants attached to the dual sides. One of its key pred
 ictions is the identification of dualpairs of elliptic stable envelopes\, 
 which are certain topological classes intimately related to elliptic quant
 um groups.
