Abstract

In order to understand the dynamics of a differential system, it is an imperative matter to establish conditions for the existence of invariant sets, such as periodic orbits. The problem of bifurcation of periodic solutions in differential systems can be often reduced to the problem of persistence of zeros of a certain function. So in this project we shall use the Lyapunov-Schmidt reduction to develop higher order bifurcation functions to control the persistence of zeros of some perturbed functions.
