Multicomplex number

The multicomplex numbers form a commutative n dimensional algebra generated by one element e which satisfies $~e^{n}=-1$. A multicomplex number x can be written as

$x=\sum _{i+0}^{n-1}x_{i}e^{i}$

with $~e^{n}=-1$ and $~x_{i}$ real. It is possible to write any multicomplex number x (with $||x||\neq 0$) in an exponential representation

$x=\sum _{i=0}^{n-1}x_{i}e^{i}=\rho \exp(\sum _{i=1}^{n-1}\Theta {}_{i}e^{i})$.

A special case of multicomplex numbers are the bicomplex numbers.
