Exact instanton-anti-instanton solutions and semiclassical expansion in the $\sigma$ model with fermions
R. G. Ismagilov
Abstract:
The effective action obtained after exact integration with respect to the fermion fields is
extremal on configurations that can be interpreted as instanton-anti-instanton solutions.
The single-loop contribution of the obtained solutions to the functional integral is
estimated.
