The core algorithm of Clifford algebra is geometric product, which consists of scalar product and outer product. It is the most important basis for geometric element topology calculation. In Clifford algebraic space C n, for any vector a, b ∈ C n, its geometric product ab is expressed as: (1) a b = a ⋅ b + a ∧ b

Webinvariant theory." Roughly, these say that the only way that tensor identities can arise in dimension n is by skewing over n + 1 indicies ( cf. the proof of Cayley-Hamilton given early in this article). Theorem B uses a geometric interpretation [3] of 1-lk as jets on G / P and invariants as differential operators invariant under G. Webinvariant theory."

Webunder the group of bijective linear maps, whereas the geometric properties of an a–ne space are invariant under the group of bijective a–ne maps, and these two groups are not isomorphic. Roughly speaking, there are more a–ne maps than linear maps. A–ne spaces provide a better framework for doing geometry. In particu-
