"... In 1988, Nemhauser and Wolsey introduced the concept of MIR inequality for mixed integer linear programs. In 1998, Wolsey defined MIR inequalities differently. In some sense these definitions are equivalent. However, this note points out that the natural concepts of MIR closures derived from these t ..."

On Time-Splitting spectral approximations for the Schrödinger equation in the semiclassical regime

by Weizhu Bao, Shi Jin, Peter A. Markowich - J. Comput. Phys , 2002
"... In this paper we study time-splitting spectral approximations for the linear Schrödinger equation in the semiclassical regime, where the Planck constant ε is small. In this regime, the equation propagates oscillations with a wavelength of O(ε), and finite difference approximations require the spatia ..."

constraints (e.g., k independent of ε, and h = O(ε)) are admissible for obtaining “correct ” observables. Finally, we address the application to nonlinear Schrödinger equations and conduct some numerical experiments to predict the corresponding admissible meshing strategies. c ○ 2002 Elsevier Science (USA) 1.

Impact of regional climate change on human health.
