  • Partial Differential Equations of Mathematical Physics

The topic of this lecture series is the mathematical analysis of the Navier-Stokes equations. These equations model the motion of viscous fluids. They are used in the modeling of weather, air flow around a wing, ocean currents, flow of viscoelastic materials and many more. Despite their wide range of application, there are still major open mathematical problems. It has not been proven yet that in three dimensions solutions always exist. Further, in case solutions exist, it is not known whether they do not contain any singularities. These are the Navier-Stokes existence and smoothness problems, which were mentioned by the Clay Mathematical Institute as part of the Millennium problems. In this course we will discuss important results in the mathematical theory of the three-dimensional Navier-Stokes equations. The lecture series will be based on the recent monograph by Robinson, Rodrigo and Sadowski: The Three-Dimensional Navier-Stokes Equations, Cambridge University Press, 2016, in particular Chapters 1-8. The book is available as an e-book at the library of the University of Würzburg.

Prerequisites: Basics of functional analysis and partial differential equations. I plan to only recall what is written in Sections 1.1-1.8. If you do not know Lebesgue and Sobolev spaces, it will be useful to study these before the term starts.

    The lecture series will take place in room SE 40, Emil-Fischer-Str. 40, Tuesday 14-16 and Thursday 10-12. The excercise classes will take place Wednesdays 8-10, also in SE 40.

[Wintersemester 2016/17

  • Research in Groups (Arbeitsgemeinschaft) on "Calculus of Variations: the vectorial case".

    Topics include lower semicontinuity of integral functionals, relaxed variational problems, notions of polyconvexity, quasiconvexity and rank-one convexity, Gamma-convergence methods etc. The focus of this Research in Groups will be on analytical methods and concepts. Nevertheless, all these mathematical topics have interesting real-world applications in nonlinear elasticity, micromagnetic materials or so-called smart materials, which I will be happy to tell more about or which can be a topic of master theses. Of course, also the analytical topics discussed can form the basis of master (or bachelor) theses.

    Prerequisites: Basics of measure theory and functional analysis, in particular weak convergence and Sobolev spaces.

    A preliminary discussion has already taken place, in which we fixed the schedule and organizational details of this Research in Groups. There will be a lecture series in SE 30 on Thursdays 10-12. There will be a blockseminar for the student's talk.

    Please contact me if you are interested in joining this Research in Groups but happen not to have attended the preliminary discussion. If you prefer to attend a Seminar (Bachelor or Master) on this topic instead of the Research in Groups, please let me know so that we can discuss how this can be done.
