A non-oscillation theorem for differential matrix systems
Journal of Mathematical Analysis and Applications, 2005 Excellently written, the paper deals with a Wintner-Hille-Opial-type nonoscillation result for the matrix differential equation \(Y^{\prime \prime }+Q(t)Y=0\), \(t\geq a\), where \(Q(t)\) is a real, \(n\times n\), continuous, symmetric matrix function.

Oscillation for Super Linear/Linear Second Order Neutral Difference Equations with Variable Several Delays [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2020 This article, is concerned with finding sufficient conditions for the oscillation and non oscillation of the solutions of a second order neutral difference equation with multiple delays under the forward difference operator, which generalize and extend ...

Necessary and sufficient conditions for oscillation of second-order differential equations with nonpositive neutral coefficients [PDF]
Mathematica Bohemica, 2021 In this work, we present necessary and sufficient conditions for oscillation of all solutions of a second-order functional differential equation of type (r(t)(z'(t))^\gamma)' +\sum_{i=1}^m q_i(t)x^{\alpha_i}(\sigma_i(t))=0, \quad t\geq t_0, where ...

Journal of Inequalities and Applications, 2019 This paper is devoted to the analysis of the oscillatory behavior of Euler type linear and half-linear differential equations. We focus on the so-called conditional oscillation, where there exists a borderline between oscillatory and non-oscillatory ...

Global analysis of three-flavor neutrino masses and mixings [PDF]
, 2005 We present a comprehensive phenomenological analysis of a vast amount of data from neutrino flavor oscillation and non-oscillation searches, performed within the standard scenario with three massive and mixed neutrinos, and with particular attention to ...
