| Abstract: | The problem of homoclinic bifurcation under perturbation is studied for the high dimensional system with nonhyperbolic equilibrium. By constructing local coordinate systems near the unperburbed homoclinic orbit, we get Poincare maps of the system in new coordinate systems, and discuss the persistence of generic homoclinic orbit and the bifurcation of periodic orbit from the homoclinic orbit for the system accompanied with transcritical bifurcation. Some known results are extended. |
