Improved Hille-Type Oscillation Criteria for Second-Order Quasilinear Dynamic Equations

open access: yesMathematics, 2022
In this work, we develop enhanced Hille-type oscillation conditions for arbitrary-time, second-order quasilinear functional dynamic equations. These findings extend and improve previous research that has been published in the literature.

Dynamic Structural Equation Models

open access: yesStructural Equation Modeling: A Multidisciplinary Journal, 2017
This article presents dynamic structural equation modeling (DSEM), which can be used to study the evolution of observed and latent variables as well as the structural equation models over time. DSEM is suitable for analyzing intensive longitudinal data where observations from multiple individuals are collected at many points in time.

Oscillation Criteria of Singular Initial-Value Problem for Second Order Nonlinear Dynamic Equation on Time Scales

open access: yesNonautonomous Dynamical Systems, 2018
By using of generalized Opial’s type inequality on time scales, a new oscillation criterion is given for a singular initial-value problem of second-order dynamic equation on time scales. Some oscillatory results of its generalizations are also presented.
