Green Function Method in Statistical Mechanics

This concise monograph is devoted to techniques of solving many-body problems in physics using the quantum-mechanical Green function method. Suitable for advanced undergraduates and graduate students of physics it requires some familiarity with the basic theory of quantum mechanics and statistical mechanics. <br>Focusing on the general method the treatment begins by establishing the connection between the Green functions and the thermodynamic and kinetic characteristics of a system. Subsequent chapters illustrate the method and apply it to different problems in the physics of condensed media including the theory of electron plasmas in solids electron-phonon interactions and ferromagnetism at finite temperatures. Seven helpful Appendixes offer supplementary information.
