Commutator Method for Averaging Lemmas

Analysis & PDE, 2019
We introduce a commutator method with multipliers to prove averaging lemmas, the regularizing effect for the velocity average of solutions for kinetic equations. This method requires only elementary techniques in Fourier analysis and shows a new range of

The center problem via averaging method

Journal of Mathematical Analysis and Applications, 2009
The averaging method has been used to study the problem of the determination of the number of hyperbolic limit cycles that can bifurcate from the period annulus of a center.

Application of the Averaging Method to the Optimal Control Problem of Non-Linear Differential Inclusions on the Finite Interval

Axioms, 2022
In this paper, we use the averaging method to find an approximate solution for the optimal control of non-linear differential inclusions with fast-oscillating coefficients on a finite time interval.

Motion Detection Using Adaptive Temporal Averaging Method

Radioengineering, 2014
Motion detection methods are widely integrated in modern intelligent video surveillance systems. Many of these methods use background subtraction techniques to separate the foreground objects from the background.

Averaging method for ordinary differential inclusions with maxima

Electronic Journal of Differential Equations, 2018
We consider ordinary differential inclusions with maxima perturbed by a small parameter and give justification of the method of averaging for this type of inclusions.

Approximate Optimal Control for a Parabolic System with Perturbations in the Coefficients on the Half-Axis

Axioms, 2022
In this paper, we use the averaging method to find an approximate solution in the optimal control problem of a parabolic system with non-linearity of the form f(t/ε,y) on an infinite time interval.

On Strutinsky's averaging method [PDF]

Nuclear Physics A, 1973
Abstract The averaging procedure in Strutinsky's method of shell corrections is formulated for a general type of averaging function. In the case of the harmonic-oscillator potential, the method is proved analytically to give the same results as semiclassical methods. For the infinite-rectangular-box potential, an uncertainty in the value of the shell

Evolution of the rotational motion of a viscoelastic planet with a core on an elliptical orbit

Российский технологический журнал, 2021
The work is devoted to the study of the evolution of the rotational motion of a planet in the central Newtonian field of forces. The planet is modeled by a body consisting of a solid core and a viscoelastic shell rigidly attached to it.
