These lectures are devoted to a discussion of the use of thermo dynamic Green's functions in describing the properties of many particle systems. These functions provide a method for discussing finitetemperature problems with no more conceptual difficulty than groundstate (i.e., zerotemperature) problems; the method is equally applicable to boson and fermion systems, equilibrium and nonequilibrium problems.
