Second-Order Containment Control of Multiagent Systems in the Presence of Uncertain Topologies with Time-Varying Delays by Fuyong Wang, Hongyong Yang, Zhongxin Liu, Zengqiang Chen

“…Moreover, the control algorithm is proposed for containment control, and the stability of the proposed containment control algorithm is studied with the aid of Lyapunov-Krasovskii function when the communication topology is jointly connected. Some sufficient conditions in terms of linear matrix inequalities (LMIs) are provided for second-order containment control with multiple stationary leaders. …”

Upper semicontinuity of uniform attractors for singular perturbed second order nonautonomous delay lattice systems by Yao Zhou, Hongliang Liu

“…Then we establish some prior uniform estimations of solutions. Finally we study the upper semicontinuity of the uniform attractors as the coefficient of second order derivative term tends to zero which showing the relationship between the uniform attractors for second order and the corresponding first order nonautonomous delay lattice systems.…”

Applied Lyapunov Stability for Some Nonlinear Stochastic Differential Equations by Nibal Sabah Abdurahman , Abdulghafoor Jasim  Salim

“… In this paper, we applied and explain the stability to some linear and  non-linear stochastic differential equations by using the Lyapunov direct second method, after finding the  stochastic differential equation which obtained by applying the (Ito-integrated formula) and the quadratic Lyapunov function be taken, we use the Lyapunov theorems to find and explain if the trivial (zero) solution are stochastically stabile (p-stable, mean square stable and stochastically asymptotically stable in the large ), then we explain the methods by some examples. …”
