Differential Equations for Elementary Particles: Beyond Duality

This theory of particles is a new constructive approach, alternative to the string theory, where the particles are not points but 3-dimensional conservative distributions of matter with a finite volumes in each fixed time instance during their propagation. Thus, it avoids the infinitary problems of the inverse square low for gravitational and electric forces, and can be used as a basis for the Einstein's unification theory. It should be especially usefull to all students and professionals in quantum mechanics.
