摘要：

The critical exponent eta is calculated in the Gross Neveu model in arbitrary dimensions to next to leading order within the 1/N expansion, by computing the skeleton equations for the propagators near the critical region. The exponent-nu is also computed and the next to leading order structure of the beta-function deduced. Consequently, the four-loop term of the anomalous dimension is determined.
