Post-Quantum Chebyshev-Type Integral Inequalities for Synchronous Functions

open access: yesMathematics, 2022
In this paper, we apply (p,q)-calculus to establish some new Chebyshev-type integral inequalities for synchronous functions. In particular, we generalize results of quantum Chebyshev-type integral inequalities by using (p,q)-integral. By taking p=1 and q→

Tensorial and Hadamard Product Inequalities for Synchronous Functions

open access: yesCommunications in Advanced Mathematical Sciences, 2023
Let $H$ be a Hilbert space. In this paper we show among others that, if $f,$ $g$ are synchronous and continuous on $I$ and $A,$ $B$ are selfadjoint with spectra ${Sp}\left( A\right) ,$ ${Sp}\left( B\right) \subset I,$ then% \begin{equation*} \left( f ...

Inequalities for D−Synchronous Functions and Related Functionals

open access: yesRevista Integración, 2020
We introduce in this paper the concept of quadruple D−synchronous functions which generalizes the concept of a pair of synchronous functions, we establish an inequality similar to Chebyshev inequality and we also provide some Cauchy-Bunyakovsky-Schwarz ...

Speed control for permanent magnet synchronous motor based on an improved extended state observer

open access: yesAdvances in Mechanical Engineering, 2018
An improved extended state observer is designed to eliminate the influences of speed control for a permanent magnet synchronous motor. The improved extended state observer is designed based on a new nonlinear function.

Fujiwara’s inequality for synchronous functions and its consequences

open access: yesBiometrical Letters, 2023
Summary The theory of inequalities is an essential tool in all fields of the theoretical and practical sciences, especially in statistics and biometrics. Fujiwara’s inequality provides relationships between expected values of products of random variables.

Certain New Chebyshev and Grüss-Type Inequalities for Unified Fractional Integral Operators via an Extended Generalized Mittag-Leffler Function

open access: yesFractal and Fractional, 2022
In this paper, by adopting the classical method of proofs, we establish certain new Chebyshev and Grüss-type inequalities for unified fractional integral operators via an extended generalized Mittag-Leffler function. The main results are more general and

Certain Inequalities Pertaining to Some New Generalized Fractional Integral Operators

open access: yesFractal and Fractional, 2021
In this paper, we introduce the generalized left-side and right-side fractional integral operators with a certain modified ML kernel. We investigate the Chebyshev inequality via this general family of fractional integral operators.

On a General Formulation of the Riemann–Liouville Fractional Operator and Related Inequalities

open access: yesMathematics, 2023
In this paper, we present a general formulation of the Riemann–Liouville fractional operator with generalized kernels. Many of the known operators are shown to be particular cases of the one we present.
