I have define the notation in my paper. If you do not read my paper, how can you comment on my paper?

Purchase a copy of ``Clifford Algebras and > Spinors,'' Perti Lounesto. Inverse of a vector is widely accepted by mathematicians and physicists. A^(-1) = 1/A = A/A^2 (where A is a vector) Please refer to: http://en.wikipedia.org/wiki/Geometric_algebra

Don't change the subject. >A^(-1) = 1/A = A/A^2 (where A is a vector) Note that the denominator is a scalar. |
