**All Spacetimes Beyond Einstein**

by Frederic P. Schuller

**Publisher**: arXiv 2011**Number of pages**: 44

**Description**:

Which geometries on a smooth manifold (apart from Lorentzian metrics) can serve as a spacetime structure? This question is comprehensively addressed from first principles in eight lectures, exploring the kinematics and gravitational dynamics of all tensorial geometries on a smooth manifold that can carry predictive matter equations, are time-orientable, and allow to distinguish positive from negative particle energies.

**Observers and Splitting Structures in Relativistic Electrodynamics**

by

**arXiv**

We introduce a relativistic splitting structure as a means to map equations of electromagnetism from curved four-dimensional space-time to 3-dimensional observer's space. We focus on mathematical structures that are motivated by the physical theory.
