Nonlinear Dynamics of Electrons in Electromagnetic and Gravitational Fields

The nonlinear dynamics of positrons in modified theories is considered in light of new hypotheses regarding the mass of charged particles and the mass of the graviton. Laws of the vertical movement of positrons in a constant magnetic field, a Barnhill–Schiff electric field, and the Earth’s gravitational field are obtained on the basis of calculations. Experiments are proposed to test these new hypotheses.
