מפגש קבוצת התיאוריה של אנרגיות גבוהות: Non-Cauchy surface foliations and their expected connection to quantum gravity theories

Abstract: 

I suggest that quantum gravity theories should involve construction of a quantum theory on non-Cauchy hypersurfaces. I propose a setup where the hypersurface direction is that of the direction of the effective non-gravitational force field at a point. I will start with a short review of works which support this idea.  I will then show a foliation of spacetime along an effective non-gravitational force field direction, and discuss the implication of this foliation on the expected properties of quantum gravity.
