The second-order partial differential wave Equation (Cauchy?s first equation of motion), derived from Newton?s force equilibrium, describes a standing wave field consisting of two waves propagating in opposite directions, and is, therefore, a ?two-way wa...

Starting from the four component-Dirac equation for free, ballistic electrons with finite mass, driven by a constant d.c. field, we derive a basic model of scalar quantum conductivity, capable of yielding simple analytic forms, also in the presence of ma...

The paper is dedicated to a mathematical simulation of the motion of a spacecraft in an elliptical orbit. The acceleration vector is limited in modulo and orthogonal to the plane of spacecraft orbit during its motion. The spacecraft motion is described u...

The analysis of many physical phenomena is reduced to the study of linear differential equations with polynomial coefficients. The present work establishes the necessary and sufficient conditions for the existence of polynomial solutions to linear differ...

The Dirac equation have been solved for the q-deformed hyperbolic Scarf potential coupled to a Coulomb-like tensor potential under the spin symmetry. The parametric generalization of the Nikiforov-Uvarov method is used to obtain the energy eigenvalues eq...
