q-Deformed Relativistic Wave Equations

Abstract

Based on the representation theory of the $q$-deformed Lorentz and Poincaré symmeties $q$-deformed relativistic wave equation are constructed. The most important cases of the Dirac-, Proca-, Rarita-Schwinger- and Maxwell- equations are treated explicitly. The $q$-deformed wave operators look structurally like the undeformed ones but they consist of the generators of a non-commu\-ta\-tive Minkowski space. The existence of the $q$-deformed wave equations together with previous existence of the $q$-deformed wave equations together with previous results on the representation theory of the $q$-deformed Poincaré symmetry solve the $q$-deformed relativistic one particle problem.
