Existence and multiplicity of weak quasi-periodic solutions for second order Hamiltonian system with a forcing term [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
In this paper, we first obtain three inequalities and two of them, in some sense, generalize Sobolev's inequality and Wirtinger's inequality from periodic case to quasi-periodic case, respectively.

A Generalized Wirtinger's Inequality with Applications to a Class of Ordinary Differential Equations [PDF]

open access: yesJournal of Inequalities and Applications, 2009
We first prove a generalized Wirtinger's inequality. Then, applying the inequality, we study estimates for lower bounds of periods of periodic solutions for a class of delay differential equations , and , where , , and and , are two given ...

Stability of port-Hamiltonian systems with mixed time delays subject to input saturation

open access: yesNonlinear Analysis, 2023
In this paper, we investigate the stability of port-Hamiltonian systems with mixed time-varying delays as well as input saturation. Three types of time delays, including state delay, input delay, and output delay, are all assumed to be bounded.

An improved delay-dependent stabilization criterion of linear time-varying delay systems: An iterative method [PDF]

open access: yes, 2023
summary:This paper presents delay-dependent stabilization criteria for linear time-varying delay systems. A less conservative stabilization criterion is derived by invoking a new Lyapunov-Krasovskii functional and then, extended reciprocally convex ...

Finite-Time Passivity Analysis of Neutral-Type Neural Networks with Mixed Time-Varying Delays

open access: yesMathematics, 2021
This research study investigates the issue of finite-time passivity analysis of neutral-type neural networks with mixed time-varying delays. The time-varying delays are distributed, discrete and neutral in that the upper bounds for the delays are ...
