✦ Synopsis

The one-electronmomentum distribution function (&ako~ for an electron gas is investigated by a diagrammatic analysis of perturbation theory. It is shown that (&ak,,) has the following exact asymptotic form for large k (k + pF; pF, the Fermi momentum): (a~oako> = $ (x\r,/x)'

x (&k8) &l(O) f ... , where gfl(0) is the zero-distance value of the spin-up-spin-down pair correlation function. The physical implications of the above asymptotic form are discussed.

Utilizing the theory of positive deΓΏnite densities we express the density of a t-random variable as the characteristic function of a convolution of two Gamma-variables. This allows us to obtain a simple interpretation and an expression for the characteristic function of the t-variable.

We present two new derivations of the Wigner distribution function for a simple harmonic oscillator Hamiltonian. Both methods are facilitated using a formula which expresses the Wigner function as a simple trace. The first method of derivation then utilizes a modification of a theorem due to Messiah
