Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Require one time-like direction in the metric signature.

How to interpret this relation type

Keep the existing data and select the subclass satisfying an additional law, existence condition, finiteness condition, or other property.

Each relation below starts at this concept.

Lorentzian manifoldGeneral relativity

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

General relativity treats a Lorentzian metric and related geometric fields as dynamical variables constrained by Einstein’s equations.

How to interpret this relation type

A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

The Kerr solution is a Lorentzian manifold with a stationary, axisymmetric metric satisfying the vacuum Einstein equation.
