очень интересно, но кватернионы ли это? или просто 2 комплексных числа?
пишут следующее:

...After the discovery of quaternions by Hamilton, Segre proposed modified quaternions so that commutative property in multiplication is possible [5]. This number system, called commutative quaternion. Commutative quaternions are decomposable into two complex variables [6]. The set of commutative quaternions
is 4− dimensional like the set of quaternions. But this set contains zero-divisor
and isotropic elements. ...

что-то последняя фраза меня настораживает. zero-divisor это не есть хорошо
