On the presumable wave nature of the time flow of Kozyrev
(Trade Science Inc., 2014-03)In this brief note we mathematically substantiate the presumable wave nature of the so-called time flow in the conception of time offered by N.A. Kozyrev. -
On the mathematical necessity of the co-existence of electromagnetic fields of the non-standard polarity with the standard electromagnetic fields in the case of the existence of Dirac monopoles
(Council for Innovative Research, 2015-03)In this brief note we adduce the mathematical rationale of the necessity of the existence of the electromagnetic field of the non-standard polarity if the magnetic charges (Dirac monopoles) exist in reality. -
The pedagogical value of the fourdimensional picture: III. Solutions to Maxwell’s equations
(IOP Publishing, 2016)We outline a regular way for solving Maxwell’s equations. We take, as the starting point, the notion of vector potentials. The rationale for introducing this notion in electrodynamics is that the set of Maxwell’s equations ... -
On unexpected difficulties in the teaching of the special theory of relativity
(CrossRef, 2016)The wide availability of information has led to the fact that students are well aware of the difficulties of existing physical theories. In this article we analyze some logical paradoxes of the special relativity theory ... -
Gauge Symmetries and gauge trnasformations for Maxwell Equations
(Sciencie Publishing GroupCoulomb gauge potentialsMaxwell equations, 2013)In a previous publication [5] we introduced gauge invariant electromagnetic potentials. However the field equations that were derived for them turn out to be the Coulomb gauge field equations. This raises the question ... -
Helmholtz Theorems, Gauge Transformations, General Covariance and the Empirical Meaning of Gauge Conditions
(Scientific Research Publishing, 2016-05)It is well known that the use of Helmholtz decomposition theorem for static vector fields C : R3 → R3 , when applied to the time dependent vector fields E : R4 → R3 , B : R4 → R3 which represent the electromagnetic field, ... -
Gauge Invariance of Gravitodynamical Potentials in the Jefimenko’s Generalized Theory of Gravitation
(Scientific Research Publishing, 2016-09)In the Jefimenko’s generalized theory of gravitation, it is proposed the existence of certain potentials to help us to calculate the gravitational and cogravitational fields, such potentials are also presumed non-invariant ... -
Some of the Complexities in the Special Theory of Relativity: New Paradoxes
(SCIENCEDOMAIN international, 2016-06)In this article we analyze some logical contradictions of the special relativity theory (SRT), concerning the time dilation and length contraction. The Lorentz transformations and the relativistic law for velocity addition ... -
On the Jefimenko’s Non-Einsteinian Clocks and Synchronicity of Moving Clocks
(Scientific Research Publishing, 2017-03-09)In this work we analyze the concept of time dilation in its application to the rate of moving clocks. The rates of two equiform elementary electromagnetic clocks of different orientations relative to their direction of ... -
The origin of the energy–momentum conservation law
(Elsevier, 2017-07)The interplay between the action–reaction principle and the energy–momentum conservation law is revealed by the examples of the Maxwell–Lorentz and Yang–Mills–Wong theories, and general relativity. These two statements ... -
On the Question of the Invariance of the Light Speed
(Scientific Research Publishing, 2017-07)This article is devoted to the key concept of modern electrodynamics—the invariance of the speed of light. The general principle of relativity is considered in detail. Some critical remarks to the relativistic invariance ... -
On the Existence of Gauge Functions for Space-Like Separations
(Academicians Research Center, 2017)In this paper we have a threefold objective. 1. To propose a method for the determination of gauge transformations. 2. to prove that some gauge transformations are local, in the sense that they are not defined all along ... -
On the violation of the invariance of the light speed in theoretical investigations
(World Scientific, 2017-11)In this review, we analyze some of the most important theoretical attempts to challenge the invariance of the light speed postulated by the Special Theory of Relativity (STR). Most of those studies, however, show that ... -
Classical Electrodynamics: The Problems in the Theoretical Description of the Intra-Dipole Radiation
(MedCrave, 2017-10-03)In our paper we would like to analyze some mathematical and physical problems which arise in the interior of an electric dipole during its oscillation along the vector of the dipole moment. A hypothesis is advanced that ... -
Spherical and Ring-Like Configurations for the Gravitodynamical Field
(Sryahwa Publications, 2018)In the present work, we write a brief exposition of the Jefimenko’s theory of gravitation. This theory arose from the analogy between the laws of gravitation and electromagnetism, that is, exist a second gravitational field ... -
Dipole moments of the tau-neutrino from the process e+e− → ν¯νγ
(Elsevier, 2014)In the framework of a Simplest Little Higgs Model (SLHM), we calculate the total cross section for the reaction e+e− → ν¯νγ and thereafter we get a limit on the characteristic energy scale of the model f , f ≥ 5.5 TeV, ... -
Limits on the electromagnetic and weak dipole moments of the tau-lepton in a 331 model
(Elsevier, 2014)Using as an input the data obtained by the L3 and OPAL Collaborations for the reaction e+e− → τ+τ−γ at the Z1-pole, we obtained bounds on the electromagnetic and weak dipole moments of the tau-lepton in the context of a ... -
Reply to ‘Comment on “Helmholtz Theorem and the V-Gauge in the Problem of Superluminal and Instantaneous Signals in Classical Electrodynamics” by A. Chubykalo et al.’ by J.A. Heras [Found. Phys. Lett. vol. 19(6) p. 579 (2006)]
(Springer, 2007-09)José A. Heras has recently raised interesting criticism [1] regarding the conclusions to our paper [2]. His main point is his assertion that the equations we derived for the solenoidal (Es ) and the irrotational (Ei ) ... -
