Structural kinematical approach in elementary particle physics

Unique approach is proposed for constructing of relativistic lepton wave equations. It is kinematical approach because it is exact results based on few conventional fundamental principles. Arising structural constituents of equations and particles are corollary of discrete symmetries or connected components of Lorentz group. Generality and accuracy of the developed method allow one to put the question of its extension on the hadron sector. The conditions for solving of the named problem are discussed such as unification of the mathematical formalism and some widely used notions
