Optimal adaptivity for non-symmetric FEM/BEM coupling

Michael Feischl

We develop a framework which allows us to prove the essential general quasi-orthogonality for the non-symmetric Johnson-Nedelec finite element/boundary element coupling. General qu…

Optimal adaptivity for a standard finite element method for the Stokes problem

Michael Feischl

We prove that the a standard adaptive algorithm for the Taylor-Hood discretization of the stationary Stokes problem converges with optimal rate. This is done by developing an abstr…

Fast random field generation with -matrices

Michael Feischl, Frances Kuo, Ian H. Sloan

We use the -matrix technology to compute the approximate square root of a covariance matrix in linear cost. This allows us to generate normal and log-normal random fields on gen…
