Abstract:
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.
