This note presents a concrete representation of stably compact spaces. This is used to give a simple, and predicative, description of the patch topology of a stably compact space (J. Pure Appl. Algebra, to appear).

โฆ Synopsis
Let G be a connected complex semisimple affine algebraic group, and let K be a maximal compact subgroup of G. Let X be a noncompact oriented surface. The main theorem of [3] says that the moduli space of flat K-connections on X is a strong deformation retraction of the moduli space of flat G-connections on X. We prove that this statement fails whenever X is compact of genus at least two.
