Weakly nonlinear nonaxisymmetric oscillations of capillary bridges at small viscosity [PDF]
, 2002 Weakly nonlinear nonaxisymmetric oscillations of a capillary bridge are considered in the limit of small viscosity. The supporting disks of the liquid bridge are subjected to small amplitude mechanical vibrations with a frequency that is close to a ...

A Review of Green's Function Methods for Tracer Timescales and Pathways in Ocean Models
Journal of Advances in Modeling Earth Systems, Volume 17, Issue 7, July 2025.Abstract Understanding advective‐diffusive dispersal of trace substances in environmental fluids like the global ocean is a ubiquitous challenge in geophysics. Since the turn of the millennium, substantial progress has been made in the theory, implementation in models, and application of such tracers in oceanography.

Asymptotic behavior of solutions of the third-order nonlinear advanced differential equations
AIMS Mathematics, 2023 The aim of this work is to study some asymptotic properties of a class of third-order advanced differential equations. We present new oscillation criteria that complete, simplify and improve some previous results.

New Oscillation Criteria for H‐Difference Equation With Oscillatory Periodic Coefficients
Mathematical Methods in the Applied Sciences, Volume 48, Issue 8, Page 8696-8701, 30 May 2025.ABSTRACT In this manuscript, new oscillation criteria are given for solutions of h‐order delay difference equation in the equation (1.1). There, four cases of p$$ p $$ are considered: for α∈ℕ$$ \alpha \in \mathbb{N} $$, as oscillatory periodic sequences with periods 2α,(2α+1)$$ 2\alpha, \left(2\alpha +1\right) $$ and (α+1)$$ \left(\alpha +1\right ...

Global attractivity without stability for Liénard type systems
International Journal of Mathematics and Mathematical Sciences, 2001 We are concerned with some conditions such as the trivial solution of a planar system of differential equations (including the Liénard system) that is globally attractive but not stable.

Monotonicity conditions in oscillation to superlinear differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2016 We consider the second order differential equation \[ \bigl(a(t)|x^{\prime}|^{\alpha}\operatorname{sgn\,}x^{\prime}\bigr)^{\prime }+b(t)|x|^{\beta}\operatorname{sgn\,}x=0 \] in the super-linear case ...

On the Finiteness of the Number of Eigenvalues of Jacobi Operators below the Essential Spectrum [PDF]
, 2004 We present a new oscillation criterion to determine whether the number of eigenvalues below the essential spectrum of a given Jacobi operator is finite or not.
