Exponentials of Cliffors: Hyperbolic, Null, and Circular Functions
July 6, 2009 1 Comment
The exponential of a cliffor is defined as
If we assume that is a scalar, then by the law of trichotomy, one and only one of the following cases is true:
.
Here,
and
Let be another spatial cliffor. If we decompose
as
,
where and
are the components of
that commute and anticommute with
,
,
.
From the definition of the exponential of in Eqs. (2a) to (2c), we can easily see that
,
.
That is, only the component of that anticommutes with
flips the sign of
; the component
that commutes with
leaves the exponential
unchaged after a reordering of the factors.
