Abstract: With his Clifford algebra of differential forms, Kaehler’s algebra addresses the overlooked manifestation of symmetry in the solutions of exterior systems. In this algebra, solutions with a given symmetry are members of left ideals generated by corresponding idempotents. These combine with phase factors to take care of all the dependence of the solution on xi and for each ∂/∂xi=0 symmetry. The maximum number of idempotents (each for a one-parameter group) that can, therefore, go into a solution is the dimensionality n of the space. This number is further limited by non-commutativity of idempotents.
We consider the tensor product of Kaehler algebra with tangent Clifford algebra, i.e. of valuedness. It has a commutative subalgebra of “mirror elements”, i.e. where the valuedness is dual to the differential form (like in dxi, but not in dxj). It removes the aforementioned limitation in the number of idempotent factors that can simultaneously go into a solution.
In the Kaehler calculus, which is based on the Kaehler algebra, total angular momentum is linear in its components, even it is not valued in tangent algebra. In particular, it is not a vector operator.
We carry Kaehler’s treatment over to the aforementioned commutative algebra. Non-commutativity thus ceases to be a limiting factor in the formation of products of idempotents representing each a one-parameter symmetry. The interplay of factors that emerges in the expanded set of such products is inimical to operator theory. For practical reasons, we stop at products involving three one-parameter idempotents —henceforth call ternary— even though the dimensionality of the all important spacetime manifold allows for four of them.
Remark: In the paper “U(1) x SU(2) from the tangent bundle” the author establishes in general terms what he claims will be an algebraic representation of quarks. In the present paper, he goes into the details, but does not yet use physical names. I understand that this will be done in his next paper, “Quarks from the tangent bundle” (I know of a preliminary version of it). The author tells me that he would gladly hear from those qualified to endorse that new paper in arXiv-HEP-theory, and might be willing to endorse it after inspecting it.
