Conformal geometry, Dirac operators, analysis on manifolds
|
Bernd Ammann is interested in geometric partial differential equations
on manifolds, partially motivated by physical problems. His works can be
roughly separated into three groups:
1. conformal geometry, in particular the Yamabe-problem, the positive
mass theorem, the kernel of the Dirac operator, bordisms.
2. pseudodifferential operators on non-compact manifolds and applications
3. estimations of eigenvalues of Dirac and Laplace operators and
relations to the generalized Weierstrass representation. |
