Abstract

The mean-field Hamiltonian for a many-fermion system is an element in a Dynamical Algebra - a classical Lie Algebra. The thermal Matsubara and T=0 Green Functions are sums of products of factors determined by certain structure constants of the algebra. These describe the automorphisms of the Algebra.
