Analysis of PDEs

Welcome!

Our group Analysis of Partial Differential Equations (Analysis of PDEs) has recently  been established  as a new research direction at the Institute of Mathematics.

The description of dynamics in terms of partial differential equations (PDEs) plays a fundamental role in physical theories, natural  sciences and applications.  In many models nonlinearities appear naturally due to self-reinforcing processes. Despite the huge variety of problems described by nonlinear PDEs, the mathematical understanding of such problems is still limited. Consequently, the development of new analytic tools is a challenging and very active area of mathematical research.

In our group, we are mainly interested in time-evolution problems, where we investigate questions concerning local and global existence, the formation of singularities in finite time and the existence and stability of special solutions. Thereby we focus on nonlinear wave equations,  Schrödinger equations and heat flows.

In our work, we are using a variety of analytic techniques, in particular tools from functional analysis, operator theory, and spectral analysis as well as ODE methods.
