Abstract

We seek to extend the application of the techniques of closed minimal surfaces to the case where they are noncompact and have a boundary, and to explore bifurcation phenomena related to these surfaces in homogeneous 3-manifolds. More specifically, we intend to address the following topics: possible elaboration of a survey about homological systoles in Riemannian manifolds, with the proposal of problems that involve ambients with group actions and generalised geometries, such as Randers metrics (Finsler); to explicitly control the topology of noncompact minimal surfaces with boundary and low index in some 3-dimensional ambients; and to apply bifurcation techniques to prove the abundancy of minimal tori in Berger spheres which are noncongruent to the Clifford torus.
