On the convergence of the quadratic method
Lyonell Boulton, Aatef Hobiny
The convergence of the so-called quadratic method for computing eigenvalue enclosures of general self-adjoint operators is examined. Explicit asymptotic bounds for convergence to i…
Convolution spline approximations for time domain boundary integral equations
Penny J Davies, Dugald B Duncan
We introduce a new "convolution spline" temporal approximation of time domain boundary integral equations (TDBIEs). It shares some properties of convolution quadrature (CQ), but in…
An exact tree projection algorithm for wavelets
Coralia Cartis, Andrew Thompson
We propose a dynamic programming algorithm for projection onto wavelet tree structures. In contrast to other recently proposed algorithms which only give approximate tree projectio…
Matrix-free GPU implementation of a preconditioned conjugate gradient solver for anisotropic elliptic PDEs
Eike Mueller, Xu Guo, Robert Scheichl +1
Many problems in geophysical and atmospheric modelling require the fast solution of elliptic partial differential equations (PDEs) in "flat" three dimensional geometries. In partic…
