Coulomb branches for quaternionic representationsQMAP Seminar

I will discuss a construction of Coulomb branches in the gauged linear sigma model for a quaternionic representation of a compact group G. This modifies the original construction of Braverman, Finkelberg and Nakajima with some topological twists dating to the early days of K-theory. Natural and intriguing speculations about a 3D firks theory and about categorification to 4D will also be mentioned.
