Title: What's the problem? Finding interesting math topics within a PhD project.
Abstract: Doing a PhD is not just about solving problems, it is also about finding the right ones! Research projects often provide a great deal of freedom, but with that freedom comes the challenge of identifying worthwhile topics to work on. Questions that are relevant, mathematically interesting, and still unsolved can be few and far between. Drawing on examples from my project on algorithms for data centers, we explore the challenge of finding the "right" problem to tackle. - Speaker: Dario Ferloni
Title: Adaptive Finite Element Methods
Abstract: The Finite Element Method (FEM) is a standard tool for the numerical approximation of partial differential equations. In this talk, we introduce the basic ideas behind FEM starting from the weak formulation of a simple elliptic model problem. We then discuss why uniform mesh refinement can be inefficient in the presence of singularities and motivate the use of adaptive mesh refinement. This leads to the Adaptive Finite Element Method (AFEM), where local error estimators are used to automatically refine the mesh in regions where the numerical error is large. Finally, we briefly discuss the role of inexact iterative solvers and the interplay between discretization and algebraic errors.
