From a Relativistic Phenomenology of Anyons to a Model of Unification of Forces via the Goldschmidt-Spencer Theory of Lie Structures

Starting from a relativistic phenomenology of anyons in crystals, we discuss the concept of relativistic interaction and the need to unify electromagnetism and gravitation within the Spencer cohomology of Lie equations. Then, from the sophisticated non-linear Spencer complex of the Poincaré and conformal Lie pseudogroups, we build up a non-linear relative Goldschmidt-Spencer complex assigned to a gauge sequence for electromagnetic and gravitational potentials and fields. Then, using a conformally equivariant Lagrangian density, we deduce, first, the two first steps of its corresponding Janet complex and second, the dual relative Goldschmidt-Spencer complex. We conclude by giving suggestions for higher unification with the weak and strong interactions and interpretations of the Lagrangian density as a thermodynamical function and quantum wave-function. ∗Institut du Non-Linéaire de Nice, UMR 129 C.N.R.S.-Université de Nice-Sophia-Antipolis, 1361 route des Lucioles, 06560 Valbonne, France.
