• Spacetime can be modeled as a 4-dimensional Lorentzian manifold.
• These spacetimes form one of the simplest classes of Lorentzian manifolds.
• Suppose a Lorentzian manifold contains a closed timelike curve ( CTC ).
• Minkowski spacetime is a simple example of a Lorentzian manifold.
• Common shapes of the HOM dip are Gaussian and Lorentzian.
• Minkowski space is thus a comparatively simple special case of a Lorentzian manifold.
• But in general, most negative determinant matrices are neither hyperbolic nor Lorentzian.
• Also some test theories of special relativity use some sort of Lorentzian framework.
• This frame can be drawn from any frame field on any Lorentzian manifold.
• Specifying a metric tensor is part of the definition of any Lorentzian manifold.
• But the Lorentzian manifolds which are also Einstein manifolds are precisely the Lambdavacuum solutions.
• There are still examples of cases when we can distinguish Lorentzian manifolds using their invariants.
• Therefore, any Lorentzian manifold containing a CTC is said to be timelike multiply connected.
• In modern physics ( especially general relativity ) spacetime is represented by a Lorentzian manifold.
• Lorentzian symmetric spaces are of this kind.
• In Lorentzian geometry, there are two kinds of orientability : space orientability and time orientability.
• A Riemannian metric is a metric with a Lorentzian metric is one with signature, or.
• One can then define what is called a generalized Wick rotation to recover the Lorentzian theory.
• The constant \ zeta is-1 for Lorentzian signature and + 1 for Euclidean signature.
• In the theory of Lorentzian manifolds, Fermi Walker differentiation is a generalization of covariant differentiation.
