Abstract

For physical problems, the well-posedness of initial-boundary-value problems is crucial. Asking this question in general relativity, is is furthermore important to understand the necessary gauge choices and constraints. As different groups and communities ask similar questions coming from different backgrounds, it is important to be able to translate between different formulations. In this talk I will explain the approach I have taken so far, based on the 3+1 Einstein system, and highlight connections to other works, hoping to spark discussions with people from other areas of research.
