After successful completion of the course, students are able to explain applications of Hamilton-Jacobi equations. Moreover, they can explain solution concepts and solution theories for Hamilton-Jacobi equations (in particular visvosity solutions, explicit solution representations).

Hamilton-Jacobi equations are fully nonlinear PDEs of the form u_t + H(nabla u,x) = 0 and they apear in the following application fields: Hamilton mechanics, front propagation (in geometry and optics), control theory, differential game theory.

Topic of the seminar:
* (extended) mathod of characteristics for smooth solutions;
* connection to hyperbolic conservation laws;
* Hopf-Lax solution formula (for H(p) convex), Legendre trnasform;
* method of vanishing viscosity;
* viscosity solutions for H(p,x) not convex (based on a maximum principle, instead of integratin by parts onto test functions)

presentation by the participating students (blackboard or beamer),
