Abstract.

In looking for a neutral element for the space E(4, H) equipped with a tensor product deformed by the (4-4-4) cube containing the Christoffel’s symbols, I discover a matrix suggesting a link with the Lorentz transformations … but not only.

I also discover the necessity to introduce time-dependant isometric metrics (among them: the FLRW ones) and I state that the conditions allowing the existence of a neutral element are compatible with a coincidence between two definitions of the Riemann-Christoffel curvature tensor: the traditional one and the one which is induced by the inner logic of the theory studying the diverse decomposition of deformed tensor products; see the document on the page: “Un tenseur de courbure”.
