... arrow over vector variables. A B C • If A is a vector, we use A (without arrow) to denote the magnitude. • Sometimes boldface is used for vector and normal font for magnitude. Thus vector=A; magnitude=A • More formally, we can indicate magnitude of a vector by vertical bars. • Thus A=|A|. Phy 221 20 ...

... columns, and usually enclosed in brackets. A matrix is real-valued (or, simply, real) if all its elements are real numbers or real-valued functions; it is complex-valued if at least one element is a complex number or a complex-valued function. If all its elements are numbers, then a matrix is called ...

Four-vector

In the theory of relativity, a four-vector or 4-vector is a vector in Minkowski space, a four-dimensional real vector space. It differs from a Euclidean vector in how its magnitude is determined. The transformations that preserve this magnitude are the Lorentz transformations, which include spatial rotations, boosts (a change by a constant velocity to another inertial reference frame), and temporal and spatial inversions. Regarded as a homogeneous space, the transformation group of Minkowski space is the Poincaré group, which adds to the Lorentz group the group of translations. The Lorentz group may be represented by 4×4 matrices.The article considers four-vectors in the context of special relativity. Although the concept of four-vectors also extends to general relativity, some of the results stated in this article require modification in general relativity.
