Ground states of self-gravitating elastic bodies

In this talk I will detail the proof of existence of static, self-gravitating elastic bodies in the non-linear theory of elasticity. Equilibrium configurations of self-gravitating elastic bodies close to the reference configuration have been constructed by Beig and Schmidt (2003) using the implicit function theorem. In contrast, the steady states considered in this talk correspond to deformations of the relaxed state with no size restriction and are obtained as minimizers of the energy functional of the elastic body.
