Abstract
We show that the gradient of a strongly differentiable function at a
point is the limit of a single coordinate-free Clifford quotient between
a multi-difference pseudo-vector and a pseudo-scalar, or of a sum of
Clifford quotients between scalars (as numerators) and vectors (as
denominators), both evaluated at the vertices of a same non-degenerate
simplex contracting to that point. Such result allows to fix a issue
with a defective definition of pseudo-scalar field in Sobczyck’s
Simplicial Calculus. Then, we provide some consequences and conjectures
implied by the foregoing results.
