TL;DR

Associative and enveloped Lie algebras that arise in physics suggest this formalism could serve as a convenient framework for formulating basic physical laws. The associative product encodes Hodge duality by multiplication with a basis element. The authors constructed an associative algebra of differential forms with division that realizes universal Clifford algebras, classified all such algebras into Nk and Sk types—including dihedral, quaternion, Majorana, complex, spinor, and Dirac—and enabled higher‑order algebra realizations in a calculationally useful setting.

Abstract

An associative algebra of differential forms with division has been constructed. The algebra of forms in each different space provides a practical realization of the universal Clifford algebra of that space. A classification of all such algebras is given in terms of two distinct types of algebras Nk and Sk. The former include the dihedral, quaternion, and Majorana algebras; the latter include the complex, spinor, and Dirac algebras. The associative product expresses Hodge duality as multiplication by a basis element. This makes possible the realization of higher order algebras in a calculationally useful algebraic setting. The fact that the associative algebras, as well as the enveloped Lie algebras, are precisely those arising in physics suggests that this formalism may be a convenient setting for the formulation of basic physical laws.
