closed under multiplication, and forms the coquaternion algebra.
In the context of quantum mechanics and spinor algebra, the biquaternions , and (or their negatives), viewed in the representation, are called Pauli matrices.
Algebraic properties.
The biquaternions have two "conjugations":
- the biconjugate or biscalar minus bivector is formula_8 and
- the complex conjugation of biquaternion coefficients formula_9
where formula_10 when formula_11
Note that formula_12
Clearly, if formula_13 then is a zero divisor. Otherwise formula_14 is defined over the
