Sharp eigenvalue enclosures for the perturbed angular Kerr-Newman Dirac operator
Lyonell Boulton, Monika Winklmeier
A certified strategy for determining sharp intervals of enclosure for the eigenvalues of matrix differential operators with singular coefficients is examined. The strategy relies o…
Stabilized mixed hp-BEM for frictional contact problems in linear elasticity
Lothar Banz, Heiko Gimperlein, Abderrahman Issaoui +1
We investigate hp-stabilization for variational inequalities and boundary element methods based on the approach introduced by Barbosa and Hughes for finite elements. Convergence of…
A priori error estimates for a time-dependent boundary element method for the acoustic wave equation in a half-space
Heiko Gimperlein, Zouhair Nezhi, Ernst P. Stephan
We investigate a time-domain Galerkin boundary element method for the wave equation outside a Lipschitz obstacle in an absorbing half-space. A priori estimates are presented for bo…
On the long-time integration of stochastic gradient systems
B. Leimkuhler, C. Matthews, M. V. Tretyakov
This article addresses the weak convergence of numerical methods for Brownian dynamics. Typical analyses of numerical methods for stochastic differential equations focus on propert…
