== Notation== |
|||
The task decription MUST be coherent with the wikipedia page. A base is (e1 e2 ... en) not (e0 e1 ...en). |
|||
e0 must be reserved to the scalar part of a multivector. Also, why use a 4-dim R^n space to define the quaternions ? The wikipedia reference uses A(0,2), with quadratic form -x1*x1 - y1*y1, algebra generated by (1,e1,e2,e1e2), ei*ei = -1 , ei*ej = - ej*ei . |
|||
Please state the algebra dimension (2^n) , n=?? in the task definition. |
