On the Two Bifurcatinos of a White-Noise Excited Hopf Bifurcation System
-
Abstract: The present work is concerned with the behavior of the second bifurcation of aHopf bifurcation system excited by white-noise. It is found that the intervention ofnoises induces a drift of the bifurcation point along with the subtantial change inbifurcation type.
