Hence we identify with the branching product is extended to ✑ ❛ coefficients. It would be misleading to recognize ‘cliffordization’ as closely tied to ‘Clifford’ algebras. Rota and Stein showed in Refs. g. the Littlewood-Richardson rule emerges as a special case. Cliffordization provides a direct and computational very efficient approach to various product formulas of deformed structures. The language of cliffordization is that of Hopf gebras. The above example using Young tableaux is not far away from our topic.

T. an underlying Graßmann algebra. The question if such representations are equivalent is known as isomorphy problem in the theory of group presentations [74]. g. using CLIFFORD [2], non grade preserving transformations of generators. This is well known from the group theory. g. t. t. ✾ . This observation is crucial for any attempt to identify algebraic expressions with geometric objects. The same will hold in QFT when identifying operator products. 4 Clifford algebras by factorization Clifford algebras can be approached in a basis free manner which for obvious reasons avoids the problems discussed in the previous section.
