Talk Title |
Causal structure of physical matter field equations |
Abstract |
The causal structure of given matter field equations provides the crucial input from which the constructive gravity program starts. It is therefore of paramount importance to successfully address a number of subtle issues, which do not arise in the simplest examples in the mathe- matical literature, but urgently must be taken into account for physically realistic models. This talk presents a recipe to handle these complications. In particular, we will focus on how to deal with non-scalar systems of equations, gauge symmetries and implicit information that needs to be made explicit before the causal structure, encoded in the so-called principal polynomial, can be calculated correctly. We will present quite remarkable examples for the importance of getting these points right in the context of the constructive gravity program. |
