On the index problem for C1-generic wild homoclinic classes
en
SHINOHARA Katsutoshi
We study the dynamics of homoclinic classes on three dimensionalmanifolds under the robust absence of dominated splittings. We prove that, C1-generically, if such a homoclinic class contains a volume-expanding periodic point, then it contains a hyperbolic periodic point whose index(dimension of the unstable manifold) is equal to two. We also furnish anexample which shows that a similar result is not always true in higherdimensions.
