Abstract
The effective Lagrangian introduced by Zimanyi and Moszkowski is used to calculate the equation of state of symmetric nuclear matter at finite densities and temperatures. The model is treated in the mean field approximation and one-loop perturbative corrections are added to the mean field value of relevant propagators. Green functions for baryons and mesons are constructed in the framework of thermo field dynamics. An effective residual interaction, with coupling coefficients which are dependent on density and temperature, is introduced. This effective coupling is used to calculate perturbative corrections to the baryon mass, the equation of state and the compressibility of the system.
