摘要：

Quantum fluctuations of instantons in the two-dimensional non-linear O(3) σ model are computed completely. The calculation of the instanton contribution is reduced to the study of the Coulomb gas. It is shown that infrared divergences disappear if we take into account the contribution of instantons having arbitrary topological number. © 1979.
