Isoperimetric Inequalities in a Boundary Value Problem in an Unbounded Domain
(1993)SAM Research ReportIn this paper a semilinear elliptic boundary value problem in the exterior of a finite domain is considered. An important example in applications is the Poisson-Boltzmann problem. Isoperimetric inequalities for a functional of the solution are proven using optimal sub- or supersolutions.Report -

Extension and simple Proof of Lekner's Summation Formula for Coulomb Forces
(1993)SAM Research ReportA summation formula is proven for a lattice sum occurring frequently in molecular dynamics calculations. It has a much faster convergence rate than the original sum. An important application is in the case of Coulomb forces.Report -

Uniqueness of Piecewise Lipschitz Continuous Solutions of the Cauchy-Problem for 2 x 2 Conservation Laws
(1993)SAM Research ReportWe prove uniqueness theorems in the class of piecewise Lipschitz continuous solutions of the Cauchy-Problem for 2 x 2 conservation laws and improve the results of DiPerna in this class.Report -
The Inverse Sturm-Liouville Problem and Finite Differences
(1993)SAM Research ReportIn this paper we give a summary of the main results in concerning the inverse Sturm-Liouville problem. We emphasize a convergence result for a Newton method based on finite difference approximation together with a correction technique first introduced by Paine, de Hoog and Anderssen.Report
