On $\phi_0-boundedness$ for the comparison differential system
안정향,An Jeong Hyang Korea Society of Industrial Information Systems 2004 한국산업정보학회논문지 Vol.9 No.4
We investigate various $\phi_0-boundedness$ and $\phi_0-Lagrange$ stability of the trivial solution of comparison differential system. We also investigated the corresponding boundedness concepts of the trivial solution of the differential system using the theory of differential inequalities through cones and the method of cone valued Lyapunov functions.
Stability of nonlinear differential system by Lyapunov method
안정향,An, Jeong-Hyang Korea Society of Industrial Information Systems 2007 한국산업정보학회논문지 Vol.12 No.5
We abtain some stability results for a very general differential system using the method of cone valued vector Lyapunov functions and conversely some sufficient conditions for existence of such vector Lyapunov functions.
On asymptotic Stability in nonlinear differential system
안정향,An, Jeong-Hyang Korea Society of Industrial Information Systems 2006 한국산업정보학회논문지 Vol.11 No.5
We investigate various $\Phi(t)-stability$ of comparison differential equations and we abtain necessary and/or sufficient conditions for the uniform asymptotic and exponential asymptotic stability of the nonlinear differential equation x'=f(t, x).
