The Graf product: a Clifford structure framework on the exterior bundle
arXiv:1712.02737 · doi:10.1007/s00006-018-0875-6
Abstract
The geometric product, defined by Graf on the space of differential forms, endows the sections of the exterior bundle by a structure that is necessary to construct a Clifford algebra. The Graf product is introduced and revisited with a suitable underlying framework that naturally encompasses a coframe in the cotangent bundle, besides the volume element centrality, the Hodge operator and the so called truncated subalgebra as well.
