Rotation group

Japanese: 回転群 - かいてんぐん(英語表記)rotation group
Rotation group
In a plane or space, rotations about a fixed point form a group. For example, in a plane, all rotations around the origin by an angle θ form a group. This transformation can be characterized as an orthogonal matrix whose coefficients have a determinant value of 1. A rotation group is a group formed by all such transformations, i.e., all orthogonal matrices. In the case of a plane, it is called a quadratic rotation group, in the case of space, it is called a cubic rotation group, and in the case of n -dimensional Euclidean space in general, it is called an n- th order rotation group.

平面や空間で,固定点を中心とした回転は群をつくる。たとえば,平面上では,原点のまわりの角 θ の回転全体は群をつくる。この変換は,係数の行列式の値が1であるような直交行列として特徴づけられる。回転群とは,このような変換,すなわち直交行列の全体がつくる群のことである。平面の場合は2次,空間の場合は3次,一般に n 次元ユークリッド空間の場合は n 次の回転群という。
