Polynomial and Pade representations of the kinetic energy component αΊ x w x T of the correlation energy density functional E are presented in this article. Two c c w x approximate local formulas similar to the Wigner form for E are investigated for c w x T . Applications of these formulas along with
Let the column vectors of X: M\_N, M<N, be distributed as independent complex normal vectors with the same covariance matrix 7. Then the usual quadratic form in the complex normal vectors is denoted by Z=XLX H where L: N\_N is a positive definite hermitian matrix. This paper deals with a representat
