A Note on the Differences of Two Positive Linear Operators

Constructive Mathematical Analysis, 2019
In the present note we find the general estimate in terms of Paltanea's modulus of continuity. In the end, we consider some examples and we apply our result for such examples to obtain the quantitative estimates for the difference of operators.

Development of identification methods for fractional differential equations with riemann-liouville fractional derivative

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
The methods for parametric identification of fractional differential operators with $\alpha \on (1, 2)$ degree according to instantaneous values of experimental observations based on the Barrett differential equation example are suggested. The methods are

On the Construction of a Variational Principle for a Certain Class of Differential-Difference Operator Equations

Современная математика: Фундаментальные направления, 2021
In this paper, we obtain necessary and sufficient conditions for the existence of variational principles for a given first-order differential-difference operator equation with a special form of the linear operator Pλ(t) depending on t and the nonlinear ...

Gender differences in use of hearing protection devices among farm operators

Noise and Health, 2016
Purpose: Although farm operators have frequent exposure to hazardous noise and high rates of noise-induced hearing loss, they have low use of hearing protection devices (HPDs).

On meromorphic equivalence of linear difference operators [PDF]

Annales de l'Institut Fourier, 1990
We consider linear difference equations whose coefficients are meromorphic at ∞ . We characterize the meromorphic equivalence classes of such equations by means of a system of meromorphic invariants. Using an approach inspired by the work of G.

Exponential Stability Criteria for Nonautonomous Difference Systems

International Journal of Mathematics and Mathematical Sciences, 2014
The aim of this paper is to characterize the exponential stability of linear systems of difference equations with slowly varying coefficients. Our approach is based on the generalization of the freezing method for difference equations combined with new ...
