Research Abstract

I tried to restrict the parameter regions in which both static and dynamic approaches give the same results for the secondextinction. In addition, it is important to show the condition on which the second extinction occurs in the former approach but not in the latter approach. Unfortunately, however, I could not obtain the clear results for these problems.
