Breaking spaces and forms for the DPG method and applications including Maxwell equations

C Carstensen, L Demkowicz… - Computers & Mathematics …, 2016 - Elsevier
Abstract Discontinuous Petrov–Galerkin (DPG) methods are made easily implementable
using “broken” test spaces, ie, spaces of functions with no continuity constraints across mesh …

An analysis of the practical DPG method

J Gopalakrishnan, W Qiu - Mathematics of Computation, 2014 - ams.org
We give a complete error analysis of the Discontinuous Petrov Galerkin (DPG) method,
accounting for all the approximations made in its practical implementation. Specifically, we …

method with optimal test functions in context of 1D and 2D convection-dominated diffusion …

A computational study of the weak Galerkin method for second-order elliptic equations

L Mu, J Wang, Y Wang, X Ye - Numerical Algorithms, 2013 - Springer
The weak Galerkin finite element method is a novel numerical method that was first

A posteriori error control for DPG methods

C Carstensen, L Demkowicz, J Gopalakrishnan - SIAM Journal on Numerical …, 2014 - SIAM
A combination of ideas in least-squares finite element methods with those of hybridized
methods recently led to discontinuous Petrov--Galerkin (DPG) finite element methods. They …

Robust DPG method for convection-dominated diffusion problems

[HTML][HTML] A robust DPG method for convection-dominated diffusion problems II: Adjoint boundary conditions and mesh-dependent test norms

J Chan, N Heuer, T Bui-Thanh, L Demkowicz - Computers & Mathematics …, 2014 - Elsevier
We introduce a DPG method for convection-dominated diffusion problems. The choice of a
test norm is shown to be crucial to achieving robust behavior with respect to the diffusion …
