Title : Minimal 2-spheres in ellipsoids via global bifurcation theory

Abstract : I will give an overview of classical results in variational Bifurcation Theory, present some applications to geometric variational problems, and discuss a concrete problem concerning the multiplicity of minimal 2-spheres inside sufficiently elongated ellipsoids.
