## Abstract The __Z__‐expansion of two‐electron systems is analyzed with the PadΓ© technique with emphasis on establishing analytical properties of the function __E__(__Z__) formally associated with the power series expansion. The concept of critical point in this connection is stressed. For this se

This paper deals with the finite-element approximation of some variational problems, namely, linear elliptic boundary value problems, variational inequalities, and quasi-variational inequalities with noncoercive operators. To prove optimal L°°-error estimates, we introduce a simple and direct argume

In this paper, we discuss convergence of the extrapolated iterative methods for solving singular linear systems. A general principle of extrapolation is presented. The semiconvergence of an extrapolated method induced by a regular splitting and a nonnegative splitting is proved whenever the coe cien
