IHP quarter on Numerical Methods for PDEs (Sept. 5-Dec. 16 2016)

Introduction

Numerical Analysis applied to the approximate solution of PDEs is a key discipline in Applied Mathematics. Over the last few years, several new paradigms have appeared, leading to entire new families of discretization methods and solution algorithms. Simultaneously, the increased complexity of the underlying physical problems and the need to use simulators in many-query scenarios has prompted the study of model reduction techniques. Finally, a whole new approach to resolution algorithms and adaptivity has been made possible by the recent advances in the context of a posteriori error analysis. The goal of this thematic quarter is to provide an opportunity to bring together leading scientists in the field of Numerical Analysis to discuss and disseminate the latest results and envisage new challenges in traditional and new application fields. The project is structured around three main topics:

• Structure-preserving discretization methods (T1)
• Model reduction (T2)
• A posteriori error analysis (T3)
