Oscillation criteria for nonlinear differential equations with $p(t)$-Laplacian [PDF]
Mathematica Bohemica, 2016 Recently there has been an increasing interest in studying $p(t)$-Laplacian equations, an example of which is given in the following form (|u'(t)|^{p(t)-2}u'(t))'+c(t)|u(t)|^{q(t)-2}u(t)= 0, \quad t>0.

Oscillation criteria for delay equations [PDF]
Proceedings of the American Mathematical Society, 2000 Summary: This paper is concerned with the oscillatory behavior of first-order delay differential equations of the form \[ x'(t)+p(t)x({\tau}(t))=0, \quad t\geq t_{0},\tag{1} \] with \(p, {\tau} \in C([t_{0}, \infty), \mathbb{R}^+)\), \(\mathbb{R}^+=[0, \infty), \tau(t)\) is nondecreasing, \(\tau(t)

Integral criteria for second-order linear oscillation
Electronic Journal of Qualitative Theory of Differential Equations, 2006 We present several new criteria for the oscillation of the second-order linear equation $ y''(t)+q(t)y(t)=0 $, in which the coefficient $ q $ may or may not change signs. The criteria involve the integral $ \int t^\gamma q(t)\, dt $ for some $ \gamma >0

Oscillation criteria for linear difference equations with several variable delays [PDF]
Opuscula Mathematica, 2021 We obtain new sufficient criteria for the oscillation of all solutions of linear delay difference equations with several (variable) finite delays. Our results relax numerous well-known limes inferior-type oscillation criteria from the literature by ...

Some comparison criteria in oscillation theory [PDF]
Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1984 AbstractThe purpose of this paper is to establish comparison criteria, by which the oscillatory and asymptotic behavior of linear retarded differential equations of arbitrary order is inherited from the oscillation of an associated second order linear ordinary differential equation.

Evidence for Neutrino Oscillations from Muon Decay at Rest [PDF]
, 1996 A search for nu_bar_mu to nu_bar_e oscillations has been conducted at the Los Alamos Meson Physics Facility using nu_bar_mu from mu+ decay at rest. The nu_bar_e are detected via the reaction (nu_bar_e,p) -> (e+,n), correlated with the 2.2 MeV gamma from (
