Abstract
The principles and the generalized equation of chemical algebra is extended to a Minkowskian substrateE endowed with its improper non-definite-positive metric, where the non-compact 6-parameter groupG of the Lorentz transformations operates. Given a map μu,u(g) = μ(gu)m(g) onG, a “line element”ds 2 is formulated at each point marked by a vectoru. Assuming “μ = 1” and “m(g) :≠ 0 ⇒g is a pure Lorentz transformation (without a spatial rotation)”, the isotropic hypothesis (m depends on a single parameter out of three inG) is first studied. In general,ds 2 does not define a Riemannian manifold unless one additional condition onm is imposed. Several relationships are established which are useful for the calculation of the metric tensor and the curvature tensor.

A speculative physical justification of the assumption m ≠ 1 is outlined. No limits for translations vt were enforced in the classical Euclidean space [1]: the same “weight”m(vt) = 1 was thus assigned to all the translations vt. In contrast, the limits 0 ,⩽v ,⩽ c enforced in the Minkowski space suggest that the “weight”m(g) of v might vary continuously and equal zero for v≽c.
