Dirac Systems
18 février 2003 @ 16:30 – 17:30 – Jochen Brüning A “Dirac system” is a model for Dirac operators which is a family of symmetric first order elliptic differential operators tied to the geometry of a Riemannian manifold. However, the model is much simpler than the Dirac operators themselves : it is merely a first order ordi- nary differential equation with operator coefficients. […]
