## Abstract A class of reference full density matrices and their reduced density matrices is presented. These density matrices are designed to be of value as references from which to describe and measure the effects of electron correlation in atoms, molecules, and solids. A given reference full den

In 1965, Fine and Wilf proved the following theorem: if (fn)nยฟ0 and (gn)nยฟ0 are periodic sequences of real numbers, of period lengths h and k, respectively, and fn = gn for 0 6 n ยก h + k -gcd(h; k), then fn = gn for all n ยฟ 0. Furthermore, the constant h + k -gcd(h; k) is best possible. In this pape
We use basic properties of infinite lower triangular matrices and the connections of Toeplitz matrices with generating-functions to obtain inversion formulas for several types of q-Pascal matrices, determinantal representations for polynomial sequences, and identities involving the q-Gaussian coeffi
