Quaternion Division Algebra

Quaternion Division Algebra. The quaternion algebra (a;b f) is a division algebra if and only if its norm form does not represent zero nontrivially, (i.e. First, b is a division algebra if and only if all the nonzeros are unit, if and only if n(fi) 6= 0 for all fi 6= 0 by.

If these properties hold, either d ’ m 2(f) or d is a division algebra.1 So we divide as q 1 / q 2 = ( q 1 q 2 ∗) / ( q 2 q 2 ∗) whenever q 2 ≠ 0.
