Let $\mathbb{R}_{p,q,r}$ be a geometric algebra with $p+q+r=n$. A bivector is an element of grade $2$, and bivectors commute when their geometric-algebra product commutes. Riesz's…

The Dirac-Hestenes equation (DHE) is considered for potentials with prescribed symmetries, using either the Cartesian gauge or a gauge exhibiting the symmetry of the potential. Con…

Inverse-expression conjecture. The inverse of a general multivector of an arbitrary Clifford algebra can always be expressed as a linear combination of a proper number of specially…
