In the paper, it is suggsted an analytical approach of the physical description of fractal metal structures. The calculatuions are based on using quasiclassical Boltzmann kinetic equation and formally introduced operations of fractional differentiati

In this paper, we find the dependence of the reaction force N(y) of a curved trough of arbitrary shape described by a function y(x). Based on the extremum condition dN/dx valid for any point of the abscissa axis, we examine the equation N(y, y', y'')

In this paper, we discuss J. Bernoulli’s brachistochrone problem and find its analytical and numerical solutions in the cases where viscous or dry friction are taken into account. We predict the existence of a point of “geometrical phase transiti

In this paper, a solution to the problem of the motion of a brachistochrone in the ndimensional Euclidean space is firstly presented. The very first formulation of the problem in a two-dimensional case was proposed by J. Bernoulli in 1696. It represe

It is proved that the solution of the quasiclassical kinetic equation for the Bose and Fermi statistics can be represented in general in the approximation of the relaxation time. Thanks to the found general solution for the distribution function f(r,

It is shown that in the case when the spontaneous polarization vector P0 and the rotational frequency vector ω of a ferroelectric sphere do not coincide, electromagnetic waves will be radiated. The intensity of the radiation is calculated as a funct

The non-linear system of dynamic equations of the movement of the ball, sliding down on rotating with frequency ω on one-dimensional gutter of arbitrary form, is obtained. From the minimum sliding time. defined by the form of this curve. Taking into
