Five Lectures on Dpg Methods

These lectures present a relatively recent introduction into the class of discontinuos Galerkin (DG) methods, named Discontinuous Petrov-Galerkin (DPG) methods. DPG methods, in which DG spaces form a critical ingredient, can be thought of as least-square methods in nonstandard norms, or as Petrov-Galerkin methods with special test spaces, or as a nonstandard mixed method. We will pursue all the...

Tanzania Development Partners Group (dpg)

1 BACKGROUND The National Forest Programme (NFP) was put in place in Tanzania in 2001 as an instrument to implement forest policy for a period of ten years (2001-10). Its ultimate objective is: "to reduce poverty and increase economic growth by managing forests sustainably without compromising environmental and cultural values.” The primary strategies that are currently implemented for realisin...

On the coupling of DPG and BEM

In this talk we present results of our recent work [2]: We develop and analyze strategies to couple the discontinuous Petrov-Galerkin method with optimal test functions to (i) least-squares boundary elements and (ii) various variants of standard Galerkin boundary elements. The procedure (i) is somehow a natural approach, because the DPG method can also be equivalently written as a least-squares...

A Spacetime Dpg Method for Acoustic Waves

A spacetime discontinuous Petrov-Galerkin (DPG) method for the linear wave equation is presented. This method is based on a weak formulation that uses a broken graph space. The wellposedness of this formulation is established using a previously presented abstract framework. One of the main tasks in the verification of the conditions of this framework is proving a density result. This is done in...
