On bifurcation for semilinear elliptic Dirichlet problems on geodesic balls
arXiv:1305.3078
Abstract
We study bifurcation from a branch of trivial solutions of semilinear elliptic Dirichlet boundary value problems on a geodesic ball, whose radius is used as the bifurcation parameter. In the proof of our main theorem we obtain in addition a special case of an index theorem due to S. Smale.
