Mathematics Institute

Applied Mathematics Seminars

Summer Term 2008/09

Organisers: Charlie Elliott, Chris Jones and Andrew Stuart

Seminars will be at 14:00 in Seminar Room D1.07, Mathematics Institute, Zeeman Building

  • Wednesday 6 May 2009
    Soeren Bartels (Institute for Numerical Simulation, University of Bonn) Approximation of Harmonic Maps and Wave Maps

Partial differential equations with a nonlinear pointwise constraint defined through a manifold occur in a variety of applications: The magnetization of a ferromagnet can be described by a unit length vector field and the orientation of the rod-like molecules that constitute a liquid crystal is often modeled by a vector field that attains its values in the real projective plane thus respecting the head-to-tail symmetry of the molecules. Other applications arise in geometric modeling, quantum mechanics, and general relativity. Simple examples reveal that it is impossible to satisfy pointwise constraints exactly by lowest order finite elements. For two model problems we discuss the practical realization of the constraint, the efficient solution of the resulting nonlinear systems of equations, and weak accumulation of approximations at exact solutions.
