Total Stability in Nonlinear Discrete Volterra Equations with Unbounded Delay

Autor: Sung Kyu Choi, Yoon Hoe Goo, Dong Man Im, Namjip Koo

Publikováno v: Abstract and Applied Analysis, Vol 2009 (2009)

We study the total stability in nonlinear discrete Volterra equations with unbounded delay, as a discrete analogue of the results for integrodifferential equations by Y. Hamaya (1990).

h-Stability of Dynamic Equations on Time Scales with Nonregressivity

Autor: Sung Kyu Choi, Yoon Hoe Goo, Namjip Koo

Publikováno v: Abstract and Applied Analysis, Vol 2008 (2008)

We study the h-stability of dynamic equations on time scales, without the regressivity condition on the right-hand side of dynamic equations. This means that we can include noninvertible difference equations into our results.

Variationally Asymptotically Stable Difference Systems

Autor: Sung Kyu Choi, Yoon Hoe Goo, Namjip Koo

Publikováno v: Advances in Difference Equations, Vol 2007 (2007)

We characterize the h-stability in variation and asymptotic equilibrium in variation for nonlinear difference systems via nÃ¢ÂˆÂž-summable similarity and comparison principle. Furthermore we study the asymptotic equivalence between nonlinear di
