Positive Definiteness and Semi-Definiteness of Even Order Symmetric Cauchy Tensors [PDF]

open access: yes, 2014
Motivated by symmetric Cauchy matrices, we define symmetric Cauchy tensors and their generating vectors in this paper. Hilbert tensors are symmetric Cauchy tensors.

Moufang Loops of Even Order

open access: yesJournal of Algebra, 1994
\textit{O. Chein} [Trans. Am. Math. Soc. 188, No. 2, 31-51 (1974; Zbl 0263.20007)] and \textit{M. Purtill} [J. Algebra 112, 122-128 (1988; Zbl 0644.20040)] investigated Moufang loops \(L\) of even order \(n\) and proved that \(L\) are groups if \(n = 2^ k\) \((0 \leq k \leq 4)\) or \(n = 2p\) (\(p\) is any prime) or \(n = 2p^ 2\).

New oscillation constraints for even-order delay differential equations [PDF]

open access: yesOpuscula Mathematica, 2023
The purpose of this paper is to study the oscillatory properties of solutions to a class of delay differential equations of even order. We focus on criteria that exclude decreasing positive solutions.

The order of a group of even order [PDF]

open access: yesProceedings of the American Mathematical Society, 2007
Let \(G\) be a group of even order and \(t\) an involution in \(G\). \textit{R. Brauer} and \textit{K. A. Fowler } [Ann. Math. (2) 62, 565-583 (1955; Zbl 0067.01004)] proved that if \(G\) is a finite simple group then \(|G|

Conditions for the Oscillation of Solutions to Neutral Differential Equations of Higher Order

open access: yesMathematics, 2023
In this research, we applied three techniques—the comparison technique, the Riccati technique, and the integral averages technique to analyze and establish various conditions and properties associated with the oscillatory behavior of even-order neutral ...

Fourth order indirect integration method for black hole perturbations: even modes [PDF]

open access: yes, 2010
On the basis of a recently proposed strategy of finite element integration in time domain for partial differential equations with a singular source term, we present a fourth order algorithm for non-rotating black hole perturbations in the Regge-Wheeler ...

Oscillation criteria for even order nonlinear neutral differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper, we consider the oscillation criteria for even order nonlinear neutral differential equations of the form $$ \left(r(t)z^{(n-1)}(t)\right)'+q(t)f(x(\sigma(t)))=0, $$ where $z(t)=x(t)+p(t)x(\tau(t)),$ $n\geq2$ is a even integer.

Even order snake resonances [PDF]

open access: yesProceedings of International Conference on Particle Accelerators, 2002
We found that the perturbed spin tune due to the imperfection resonance plays an important role in beam depolarization at snake resonances. We also found that even order snake resonances exist in the overlapping intrinsic and imperfection resonances. Due to the perturbed spin tune shift of imperfection resonances, each snake resonance splits into two. >

Even Order Half-Linear Differential Equations with Regularly Varying Coefficients

open access: yesMathematics, 2020
We establish nonoscillation criterion for the even order half-linear differential equation (−1)nfn(t)Φx(n)(n)+∑l=1n(−1)n−lβn−lfn−l(t)Φx(n−l)(n−l)=0, where β0,β1,…,βn−1 are real numbers, n∈N, Φ(s)=sp−1sgns for s∈R, p∈(1,∞) and fn−l is a regularly varying (
