Design and Numerical Solutions of a Novel Third-Order Nonlinear Emden–Fowler Delay Differential Model

open access: yes, 2020
In this study, the design of a novel model based on nonlinear third-order Emden–Fowler delay differential (EF-DD) equations is presented along with two types using the sense of delay differential and standard form of the second-order EF equation.

Oscillatory behavior of third order nonlinear difference equation with mixed neutral terms

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
In this paper, we obtain some new sufficient conditions for the oscillation of all solutions of the third order nonlinear neutral difference equation of the form \begin{equation*} \Delta^3 \left(x_n+b_n x_{n-\tau_{1}}+c_n x_{n+\tau_{2}}\right)^{\alpha} =

Drell-Yan Cross Section to Third Order in the Strong Coupling Constant.

open access: yesPhysical Review Letters, 2020
We present phenomenological results for the inclusive cross section for the production of a lepton pair via virtual photon exchange at next-to-next-to-next-to-leading order in perturbative QCD.

Higgs Boson Production in Bottom-Quark Fusion to Third Order in the Strong Coupling.

open access: yesPhysical Review Letters, 2020
We present the inclusive cross section at next-to-next-to-next-to-leading order (N^{3}LO) in perturbative QCD for the production of a Higgs boson via bottom-quark fusion.

Oscillation of Third-Order Differential Equations with Advanced Arguments

open access: yesMathematics, 2023
The main objective of this work was to study some oscillatory and asymptotic properties of a new class of advanced neutral differential equations. Using new relations to link the solution and its corresponding function, we introduced new oscillatory ...

Realization of an Acoustic Third-Order Topological Insulator. [PDF]

open access: yesPhysical Review Letters, 2019
The recent discovery of higher-order topological insulators (TIs) has opened new possibilities in the search for novel topological materials and metamaterials. Second-order TIs have been implemented in two-dimensional (2D) systems exhibiting topological "

On a third-order phase transition [PDF]

open access: yesCommunications in Mathematical Physics, 1983
The asymptotic behaviour of random variables of the general form $$\ln \sum\limits_{i = 1}^{\kappa ^N } {\exp (N^{1/p} \beta \zeta _i )} $$ with independent identically distributed random variables ζi is studied. This generalizes the random energy model of Derrida.

Demonstration of a third-order hierarchy of topological states in a three-dimensional acoustic metamaterial [PDF]

open access: yesScience Advances, 2019
A 3D acoustic higher-order topological metamaterial supports a hierarchy of topological boundary states. Classical wave systems have constituted an excellent platform for emulating complex quantum phenomena, such as demonstrating topological phenomena in

Expanding the Applicability of a Third Order Newton-Type Method Free of Bilinear Operators

open access: yesAlgorithms, 2015
This paper is devoted to the semilocal convergence, using centered hypotheses, of a third order Newton-type method in a Banach space setting. The method is free of bilinear operators and then interesting for the solution of systems of equations.

A multipoint method of third order [PDF]

open access: yesJournal of Optimization Theory and Applications, 1969
LetF be a mapping of the Banach spaceX into itself. A convergence theorem for the iterative solution ofF(x)=0 is proved for the multipoint algorithmxn+1=xn−o(xn), where $$\phi (x) = F\prime_x^{ - 1} \left[ {F(x) + F\lgroup {x - F\prime_x^{ - 1} F(x)} \rgroup} \right]$$ andF′x is the Frechet derivative ofF.
