Abstract
A non-Archimedean analytic space is an avatar for a degeneration of varieties. A skeleton, or tropicalisation, is an object that captures leading order information about degenerations. It is therefore natural to associate skeletons to non-Archimedean spaces.
In this talk I will outline a Grothendieckian approach to unifying the study of these skeletons with those appearing in tropical geometry and mirror symmetry.
