... that the corresponding field theory be predictive and that there be a well-defined notion of observers and positive energy. From that we will find that there are four conditions that must be fulfilled by every tensorial background in order to be a viable spacetime structure which will then be called ...

Vectors exist at a single point in spacetime and can be thought of as tangent vectors at that point, thus the collection of all vectors at a given point, the tangent space, all lie on some subspace which is tangent at th ...

Noether's theorem
Noether's (first) theorem states that every differentiable symmetry of the action of a physical system has a corresponding conservation law. The theorem was proven by German mathematician Emmy Noether in 1915 and published in 1918. The action of a physical system is the integral over time of a Lagrangian function (which may or may not be an integral over space of a Lagrangian density function), from which the system's behavior can be determined by the principle of least action.Noether's theorem has become a fundamental tool of modern theoretical physics and the calculus of variations. A generalization of the seminal formulations on constants of motion in Lagrangian and Hamiltonian mechanics (developed in 1788 and 1833, respectively), it does not apply to systems that cannot be modeled with a Lagrangian alone (e.g. systems with a Rayleigh dissipation function). In particular, dissipative systems with continuous symmetries need not have a corresponding conservation law.
