On Mathematical Defect in Demonstration of Convection Theorem: Implications For Continuum Mechanics and Other Classical Field Theories
R. Smirnov-Rueda
Serious mathematical defect in the important kinematics theorem known in continuum mechanics as Convection (or Transport) Theorem is reported. We claim that the traditional demonst…

On Two Complementary Types of Directional Derivative and Flow Field Specification in the Classical Field Theory
R. Smirnov-Rueda
We discuss a general definition of directional derivative of any tensor flow field and its practical applications in physics. It is shown that both Lagrangian and Eulerian descript…

On the difference between the charge-free and the charge-neutral solutions of Maxwell equations
Andrew E. Chubykalo, Hector A. Munera, Roman Smirnov-Rueda
It is conventionally believed that solutions of so called "free" Maxwell equations for \varrho=0 (density of charge) describe the free electromagnetic field in empty space (if one…
