**Geometric Wave Equations**

by Stefan Waldmann

**Publisher**: arXiv 2012**Number of pages**: 279

**Description**:

In these lecture notes we discuss the solution theory of geometric wave equations as they arise in Lorentzian geometry: for a normally hyperbolic differential operator the existence and uniqueness properties of Green functions and Green operators is discussed including a detailed treatment of the Cauchy problem on a globally hyperbolic manifold both for the smooth and finite order setting.
