User:Slizovskiy/Instantonic field theories

Instantonic field theories are a class of quantum field theories defined by localization on the moduli space of generalized instantons.

Several theories of such type are well-known. Among them are the $$\beta\gamma-bc$$ system, the topological sector of it corresponds to Gromov-Witten  theory in two dimensions and in 4 dimensions one may consider $${\mathcal N}=2 $$ twisted Super Yang-Mills  theory   and   with topological sector  being the Donaldson theory.

Simplest example
The simplest example is Supersymmetric quantum mechanics, or Morse theory
