Quantum fluctuations in the one-instanton sector of the CP$^{n-1}$ model
Within the two-dimensional CP/sup n-1/ model the authors 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...
