Let H be a linear space over the real number field R with four elements 1, i, j, and k as the basis, with 1 as the identity element for multiplication. For the quaternion x in (4), the quaternion a1-bi-cj-dk is written as and is called the conjugate quaternion of x. x=0⇔N(x)=0 [Tsuneo Kanno] [Reference] |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
