A Finite‐Time Non‐Singular Fast Terminal Sliding Mode Control of Wheeled Mobile Robots With Prescribed Performance

open access: yesIET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
This paper combines a prescribed performance function with a non‐singular fast terminal sliding mode control technique to improve wheeled mobile robots' control performance under wheel slipping, wheel skidding, and external disturbances. A novel prescribed performance non‐singular fast terminal sliding function and a novel finite‐time prescribed ...

Derivatives of the Hurwitz Zeta function for rational arguments

open access: yesJournal of Computational and Applied Mathematics, 1998
The functional equation for the Hurwitz Zeta function ζ(s,a) is used to obtain formulas for derivatives of ζ(s,a) at negative odd s and rational a. For several of these rational arguments, closed-form expressions are given in terms of simpler transcendental functions, like the logarithm, the polygamma function, and the Riemann Zeta function.

Log-tangent integrals and the Riemann zeta function

open access: yesMathematical Modelling and Analysis, 2019
We show that integrals involving the log-tangent function, with respect to any square-integrable function on  , can be evaluated by the harmonic series. Consequently, several formulas and algebraic properties of the Riemann zeta function at odd positive ...

A Fractional Order Model for HIV/AIDS With Treatment and Optimal Control Using Caputo Derivative

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
In this paper, we are concerned with a deterministic Caputo fractional derivative mathematical model of HIV/AIDS with treatment and optimal control. We formulate a mathematical model that contains six compartments (including primary infection and treatment) and show that the model is well‐posed. We calculate the reproduction number and free and endemic

A discrete version of the Mishou theorem related to periodic zeta-functions

open access: yesMathematical Modelling and Analysis
In the paper, we consider simultaneous approximation of a pair of analytic functions by discrete shifts and of the absolutely convergent Dirichlet series connected to the periodic zeta-function with multiplicative sequence a, and the periodic Hurwitz ...

Euler Numbers and Polynomials Associated with Zeta Functions

open access: yesAbstract and Applied Analysis, 2008
For s∈ℂ, the Euler zeta function and the Hurwitz-type Euler zeta function are defined by ζE(s)=2∑n=1∞((−1)n/ns), and ζE(s,x)=2∑n=0∞((−1)n/(n+x)s). Thus, we note that the Euler zeta functions are entire functions in whole complex s-plane, and these zeta ...

Some Relations of the Twisted q-Genocchi Numbers and Polynomials with Weight α and Weak Weight β

open access: yesAbstract and Applied Analysis, 2012
Recently many mathematicians are working on Genocchi polynomials and Genocchi numbers. We define a new type of twisted q-Genocchi numbers and polynomials with weight 𝛼 and weak weight 𝛽 and give some interesting relations of the twisted q-Genocchi ...

A new generalization of the Riemann zeta function and its difference equation

open access: yesAdvances in Difference Equations, 2011
We have introduced a new generalization of the Riemann zeta function. A special case of our generalization converges locally uniformly to the Riemann zeta function in the critical strip.

On extended Hurwitz–Lerch zeta function

open access: yesJournal of Mathematical Analysis and Applications, 2017
Abstract This paper investigates an extended form of a beta function B p , q ( x , y ) . We first study the convergence problem of the function B p , q ( x , y ) and consider the completely monotonic and log-convex properties of this function. As a result, we obtain a pair of Laguerre type inequalities. Next,
