... In this section, we prove the classical finiteness theorems for a number ring R: the Picard group Pic(R) is a finite group, and the unit group R∗ is in many cases finitely generated. These are not properties of arbitrary Dedekind domains, and the proofs rely on the special fact that number rings can ...

... The second way is by means of a magnitude and a direction. The magnitude is the length of the line segment and the direction is the direction in which the vector is headed, denoted by an arrow. Vectors are represented in different ways. They may be typed in bold such as a, or as a letter with a line ...

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.
