WebThe term Hopf bifurcation (also sometimes called Poincar´e-Andronov-Hopf bifurcation) refers to the local birth or death of a periodic solution (self-excited oscillation) from an equilibrium as a parameter crosses a critical value. WebThe integral expressions for the Wiener–Hopf factors φ± q are quite complicated; however, in the case of stable process it is possible to obtain explicit formulas for a dense class of parameters (see [17]). It is remarkable that in some cases we can compute Wiener–Hopf factors explicitly with the help of factorization identity (2). WebHopf bifurcations are local phenomena; they describe the creation of limit cycles near a fixed point. As the bifurcation parameter approaches some critical value, the limit cycle … injection clinic for back pain
