A priori error analysis of high-order LL* (FOSLL*) finite element methods
Brendan Keith
A number of non-standard finite element methods have been proposed in recent years, each of which derives from a specific class of PDE-constrained norm minimization problems. The m…

The surrogate matrix methodology: Accelerating isogeometric analysis of waves
Daniel Drzisga, Brendan Keith, Barbara Wohlmuth
The surrogate matrix methodology delivers low-cost approximations of matrices (i.e., surrogate matrices) which are normally computed in Galerkin methods via element-scale quadratur…

The surrogate matrix methodology: Low-cost assembly for isogeometric analysis
Daniel Drzisga, Brendan Keith, Barbara Wohlmuth
A new methodology in isogeometric analysis (IGA) is presented. This methodology delivers low-cost variable-scale approximations (surrogates) of the matrices which IGA conventionall…
