Si avvisa che in data 10/05/2021 alle ore 17, nell'ambito delle<br>
iniziative del Seminario Matematico e Fisico di Milano, si svolgerà on<br>

<br>
Titolo: "The DPG Method for Convection-Reaction Problems"<br>
Relatore: Leszek Demkowicz, Oden Institute, The University of Texas at<br>
Austin<br>
Abstract:<br>
We present a progress report on the development of Discontinuous<br>
Petrov-Galerkin methods for the convection-reaction problem in context<br>
of time-stepping and space-time discretizations of Boltzmann equations<br>
[1]. The work includes a complete analysis for both conforming (DPGc)<br>
and non-nonconforming (DPGd) versions of the DPG method employing<br>
either globally continuous or discontinuous piece-wise polynomials to<br>
discretize the traces. The results include construction of a local<br>
Fortin operator for the case of constant convection and a global<br>
discrete stability analysis for both DPGc and DPGd methods. The<br>
theoretical findings are illustrated with numerous numerical<br>
experiments in two space dimensions. This is a joint work with Nathan<br>
Roberts from Sandia National Laboratories.<br>
