Quantum Observables in low regularity spacetimes

In this talk I will describe how to construct the algebra of observables of a quantized scalar field when the spacetime metric is not smooth. I will show the main difference with the smooth case, the technical difficulties that arise and how we addressed them.

This is joint work with G. Hörmann, C. Spreitzer and J. Vickers.
