Exact Second-Order Structure-Function Relationships [PDF]

, 2002
Equations that follow from the Navier-Stokes equation and incompressibility but with no other approximations are "exact.". Exact equations relating second- and third-order structure functions are studied, as is an exact incompressibility condition on the

Oscillatory behavior of solutions of second-order non-linear differential equations with mixed non-linear neutral terms

Frontiers in Applied Mathematics and Statistics
This study primarily seeks to expand upon these developments by encompassing neutral differential equations of mixed type, incorporating both delay and advanced terms, particularly in the case of the canonical operator.

Oscillatory behavior of the second order noncanonical differential equations

Electronic Journal of Qualitative Theory of Differential Equations, 2019
Establishing monotonical properties of nonoscillatory solutions we introduce new oscillatory criteria for the second order noncanonical differential equation with delay/advanced argument \begin{equation*} (r(t)y'(t))'+p(t)y(\tau(t))=0. \end{equation*}

New Criteria for Sharp Oscillation of Second-Order Neutral Delay Differential Equations

Mathematics, 2021
In this paper, new oscillation criteria for second-order half-linear neutral delay differential equations are established, using a recently developed method of iteratively improved monotonicity properties of a nonoscillatory solution. Our approach allows
