We study internal structure of the Kemmer–Duffin–Petiau equations for spin-0 and spin-1 mesons. We demonstrate, that the Kemmer–Duffin–Petiau equations can be splitted into constituent equations, describing particles with definite mass and broken Lorentz symmetry. We also show that solutions of the three-component constituent equations fulfill the Dirac(More)
Dynamics near the grazing manifold and basins of attraction for a motion of a material point in a gravitational field, colliding with a moving motion-limiting stop, are investigated. The Poincare map, describing evolution from an impact to the next impact, is derived. Periodic points are found and their stability is determined. The grazing manifold is(More)
