Colloquium

Finite element systems with applications

Thursday, March 5, 2015 at 3:30p.m.
Professor Snorre Christiansen (University of Oslo)
Abstract: "Finite element systems" is a framework for analysing and constructing mixed finite element spaces. The framework gives a unified presentation of known spaces such as the Raviart-Thomas-Nedelec spaces, in terms of inverse systems of differential complexes. It was introduced to construct new finite element spaces on general polytopal meshes, where it provides spaces of minimal dimension subject to the constraint of containing certain polynomials. It can also be used to construct parameter dependent spaces adapted to singular perturbations such as vanishing viscosity problems.
