A model for pulsar radiation at high radio-frequencies is presented. it is argued that the reason for the appearance of the break frequency may be the existence of a hollow-zone near the magnetic axis where the strong coherent radiation is not produced. This model explains the occurrence of the break frequency at approximately the same values for component separation, mean spectrum and the modulation index.
Some structural features underlying the theory of fields in Finsler spaces are considered by taking into account the intrinsic behaviour of the internal variable (\(y\)) associated with each point. The following three themes are considered: A new “parallelism” of \(y\) (i.e., \(\delta y\)) representing the intrinsic behaviour of \(y\); The conservation laws for the fields in some special Finsler spaces; The micro-gravitational field as a typical example of the Finslerian field.
The metric hypothesis of the unifield field theory of gravitation and electromagnetism is derived alongside the other field equations from a variational principle.
Predictions of the Drell–Yan model in hadroproduction of dimuons are reviewed. A comparison is made with the experimental situation, both actual and in the near future.
The goal of this paper is to review experiments, planned or in progress, to study the instability of the nucleon with special emphasis on those experiments which have yielded some preliminary results.
The Galilei-invariant first order differential equations are obtained. They describe the spin-orbit coupling of arbitrary spin particle with the external electromagnetic field. It is thus shown that such a coupling is not a purely relativistic effect and may be described within the framework of non-relativistic quantum mechanics. The equations obtained generalize those proposed by Levy–Leblond and Hurley.
If the cosmological equations can be reduced to the form of a dynamic system, the space of all their solutions is a Banach space. The influence of different parameters on the dynamics of the world models can be easily studied by means of the Banach metric. The method is tested for the Friedman cosmological models “perturbed” by the bulk viscosity.
Effective lagrangian of QED at high temperature in the one-loop approximation is studied. The connection with the Johnson–Baker–Willey function \(F^{[1]}\) is emphasized. The connection between the effective lagrangian at high density and the renormalized photon propagator at small distances is also postulated.
