===================================


Buongiorno a tutti,

Si avvisa che in data 10/05/2021 alle ore 17, nell'ambito delle
iniziative del Seminario Matematico e Fisico di Milano, si svolgerà on
line il seguente seminario:

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