A similar structure should also exist for the Einstein–Maxwell–Dirac equations system, which is the (super)classical limit of quantum electrodynamics, and for the Einstein–Yang–Mills–Dirac system, which is the (super)classical limit of the standard model.
Podobná struktura by měla existovat i v systému Einstein-Maxwell-Diracových rovnic, kterou jsou (super) klasickou limitou kvantové elektrodynamiky, a Einstein-Yang-Mills-Diracova systému, což je (super) klasická limita standardního modelu.
