Query: Skeleta in non-Archimedean and tropical geometry   I describe an algebro-geometric theory of skeleta, which provides a unified
setting for the study of tropical varieties, skeleta of non-Archimedean
analytic spaces, and affine manifolds with singularities. Skeleta are spaces
equipped with a structure sheaf of topological semirings, and are locally
modelled on the spectra of the same. The primary result of this paper is that
the topological space underlying a non-Archimedean analytic space may locally
be recovered from the sheaf of `pointwise valuations' of its analytic
functions.
