Book chapter

Coulomb branches of 3-dimensional gauge theories and related structures

P. 1-52.
Braverman A., Michael Finkelberg.

These are (somewhat informal) lecture notes for the CIME summer
school “Geometric Representation Theory and Gauge Theory” in June 2018. In
these notes we review the constructions and results of Braverman et al. (Adv Theor
Math Phys 22(5):1017–1147, 2018; Adv Theor Math Phys 23(1):75–166, 2019;
Adv Theor Math Phys 23(2):253–344, 2019) where a mathematical definition of
Coulomb branches of 3d N = 4 quantum gauge theories (of cotangent type)
is given, and also present a framework for studying some further mathematical
structures (e.g. categories of line operators in the corresponding topologically
twisted theories) related to these theories.
