摘要：

Within the two-dimensional CPn-1 model we calculate the instanton density function in the dilute-gas limit by studying the quantum fluctuations in the one-instanton sector in the one-loop approximation. The result disagrees with the 1 n expansion. Green functions in the one-instanton background are displayed. © 1979.
