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).

BOUNDEDNESS IN NONLINEAR PERTURBED DIFFERENTIAL SYSTEMS VIA t∞-SIMILARITY
Autor: Dong Man Im, Yoon Hoe Goo
Publikováno v: Korean Journal of Mathematics. 24:723-736
This paper shows that the solutions to nonlinear perturbed differential system $$ y'=f(t,y)+\int_{t_0}^tg(s,y(s))ds+h(t,y(t),Ty(t)) $$ have bounded properties. To show the bounded properties, we impose conditions on the perturbed part $\int_{t_0}^tg(

Factor analysis and structural equation model for patent analysis: a case study of Apple’s technology
Autor: Dong Man Im, Jong Min Kim, Sunghae Jun
Publikováno v: Technology Analysis & Strategic Management. 29:717-734
In this study, we analyse patent data for technology analysis (TA) because patents are rich in information on developed technology. The results of TA can be used to perform more efficient research and development (R&D) planning. Most companies are tr

UNIFORMLY LIPSCHITZ STABILITY AND ASYMPTOTIC PROPERTY OF PERTURBED FUNCTIONAL DIFFERENTIAL SYSTEMS
Autor: Yoon Hoe Goo, Dong Man Im
Publikováno v: Korean Journal of Mathematics. 24:1-13
This paper shows that the solutions to the perturbed functional differential system \begin{eqnarray*} y'=f(t,y)+\int_{t_0}^tg(s,y(s),Ty(s))ds \end{eqnarray*} have uniformly Lipschitz stability and asymptotic property. To show these properties, we imp
