Complementary Filter‐Based Incremental Nonlinear Model Following Control Design for a Tilt‐Wing UAV
International Journal of Robust and Nonlinear Control, Volume 35, Issue 4, Page 1596-1615, 10 March 2025.ABSTRACT This article presents an incremental nonlinear model following control (INMFC) strategy for a tilt‐wing vertical take‐off and landing (VTOL) unmanned aerial vehicle (UAV). To ensure a good and robust regulation performance, a two‐loop feedback controller, based on the incremental backstepping (IBS) methodology, is used to handle uncertainties ...

Hurwitz numbers for reflection groups III: Uniform formulae
Journal of the London Mathematical Society, Volume 111, Issue 3, March 2025.Abstract We give uniform formulae for the number of full reflection factorizations of a parabolic quasi‐Coxeter element in a Weyl group or complex reflection group, generalizing the formula for the genus‐0 Hurwitz numbers. This paper is the culmination of a series of three.

Efficient Solution of Sequences of Parametrized Lyapunov Equations With Applications
Numerical Linear Algebra with Applications, Volume 32, Issue 1, February 2025.ABSTRACT Sequences of parametrized Lyapunov equations can be encountered in many application settings. Moreover, solutions of such equations are often intermediate steps of an overall procedure whose main goal is the computation of trace(EX)$$ \mathrm{trace}(EX) $$, where X$$ X $$ denotes the solution of a Lyapunov equation and E$$ E $$ is a given ...

On a generalization of Euler's constant [PDF]
Surveys in Mathematics and its Applications, 2021 A one parameter generalization of Euler's constant γ from [Numer. Algorithms 46(2) (2007) 141--151] is investigated, and additional expressions for γ are derived.

PDE‐based containment control of linear multi‐agent systems
International Journal of Robust and Nonlinear Control, Volume 35, Issue 3, Page 743-769, February 2025.Abstract This contribution considers the containment control problem for linear multi‐agent systems (MAS) using continuum models in form of linear parabolic PDEs. For this, a networked controller is designed, that ensures the asymptotic convergence of finite‐dimensional agents into a containment area specified by dynamic leaders. This problem is traced

Derivatives of the Hurwitz Zeta function for rational arguments
Journal 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.

International Journal for Numerical Methods in Engineering, Volume 126, Issue 2, 30 January 2025.ABSTRACT This paper focuses upon the single‐step multi‐stage time integration methods for second‐order time‐dependent systems. Firstly, a new and novel generalization of the Runge‐Kutta (RK) and Runge‐Kutta‐Nyström (RKN) methods is proposed, featuring an advanced Butcher table for designing new and optimal algorithms.

A Probabilistic Interpretation of the Hurwitz Zeta Function
Advances in Mathematics, 1993 AbstractPresented in a continuous extension of a measure used by Sal Golomb to define a probability on the sample space of natural numbers. The extension is a probability measure which holds several characteristic in common with Golotnb′s measure but on the sel (1, ∞ ).

On the distribution of zeros of the Hurwitz zeta-function [PDF]
Mathematics of Computation, 2007 Assuming the Riemann hypothesis, we prove asymptotics for the sum of values of the Hurwitz zeta-function ζ(s, a) taken at the nontrivial zeros of the Riemann zeta-function ζ(s) = ζ(s, 1) when the parameter a either tends to 1/2 and 1, respectively, or is fixed; the case a = 1/2 is of special interest since ζ(s, 1/2) = (2 s - 1)ζ(s).

International Journal of Robust and Nonlinear Control, Volume 35, Issue 1, Page 324-342, 10 January 2025.Abstract This article investigates the distributed mean square output tracking problem of heterogeneous multi‐agent systems with Markovian switching topologies and infinite transmission delays. The main challenge of the concerned problem arises from how to deal with Markovian switching topologies and infinite transmission delays simultaneously. A novel
