Lie Groups of Fourier Integral Operators on Open Manifolds

open access: yes, 2001
: We endow the group of invertible Fourier integral operators on an open manifold with the structure of an ILH Lie group. This is done by establishing such structures for the groups of invertible pseudodifferential operators and contact transformations ...

The twistor equation in Lorentzian spin geometry

open access: yes
In this paper we discuss the twistor equation in Lorentzian spin geometry. In particular, we explain the local conformal structure of Lorentzian manifolds, which admit twistor spinors inducing lightlike Dirac currents.
