The Minkowski inner product is not an inner product, since it has non-zero null vectors. Since it is not a definite bilinear form it is called indefinite. The Minkowski metric η is the metric tensor of Minkowski space. It is a pseudo-Euclidean metric, or more generally, a constant pseudo-Riemannian metric in Cartesian coordinates.
Product of vectors in Minkowski space is an example of indefinite inner product, although, technically speaking, it is not an inner product according to the standard definition above. Minkowski space has four dimensions and indices 3 and 1 (assignment of "+" and "−" to them differs depending on conventions ).
Both the original set of axes and the primed set of axes have the property that they are orthogonal with respect to the Minkowski inner product or relativistic dot product. The original position on your time line (ct) is perpendicular to position A, the original position on your mutual timeline (x) where (t) is zero.
In mathematics, specifically the field of algebraic number theory, a Minkowski space is a Euclidean space associated with an algebraic number field. [1] If K is a number field of degree d then there are d distinct embeddings of K into C. We let K C be the image of K in the product C d, considered as equipped with the usual Hermitian inner product.
Calculating the Minkowski norm squared of the four-momentum gives a Lorentz invariant quantity equal (up to factors of the speed of light c) to the square of the particle's proper mass: = = = + | | = where = is the metric tensor of special relativity with metric signature for definiteness chosen to be (–1, 1, 1, 1).

A two-dimensional real vector space with the Minkowski inner product is called (1 + 1)-dimensional Minkowski space, often denoted ,. Just as much of the geometry of the Euclidean plane R 2 {\displaystyle \mathbb {R} ^{2}} can be described with complex numbers, the geometry of the Minkowski plane R 1 , 1 {\displaystyle \mathbb ...
