SEMINARIO DI MATEMATICA APPLICATA

Martedi` 20 Febbraio 2018, ore 14:00 precise,
nell'Aula di Dottorato del Dipartimento di Matematica
Via Saldini 50, Milano

il Dott. Fernando Gaspoz
dell'Technische Universität Dortmund

terra` un seminario dal titolo:

H^1-stability of the L^2-projection and applications

Sunto:

The L^2-projection onto discrete spaces plays an essential role in the
analysis of finite element discretizations. On uniform grids H^1-
stability of the L^2-projection can easily be deduced by an inverse
estimate. This simple proof hinges on the fact that the minimal mesh-
size is comparable to the maximal mesh-size. We provide a technique
that sidesteps this restriction and proves the stability in H^1 of the
L^2-projection for piecewise continuous Finite Element Spaces for a
class of adaptive meshes. We also present some new applications of this
estimate.

Joint work with Claus-Justus Heine (University of Stuttgart, Germany)
