## Abstract Most electronic structure methods express the wavefunction as an expansion of __N__βelectron basis functions that are chosen to be either Slater determinants or configuration state functions. Although the expansion coefficient of a single determinant may be readily computed from configu
The aim of this paper is to give a bivariate asymptotic expansion of the coefficient \(y_{n k}=\left[x^{n}\right] y(x)^{k}\), where \(y(x)=\sum y_{n} x^{n}\) has a power series expansion with non-negative coefficients \(y_{n} \geqslant 0\). Such expansions are known for \(k / n \in[a, b]\) with \(a>
