Abstract:
Finite element methods are numerical methods that approximate solutions to
PDEs using functions on a mesh representing the problem domain.
Discontinuous-Petrov Galerkin Methods are a class of finite element
methods that are aimed at achieving stability of the Petrov-Galerkin
approximation through a careful selection of the associated trial and test
spaces. Recent methods developed by Jay Gopalkrishnan and Lezscek
Demcowicz generate 'optimal test functions' from the trial spaces that
approach the desired optimal stability. In this talk, I will present an
introduction to the Discontinuous Petrov-Galerkin Method using optimal
test functions, as well as suggest further areas of study.
