Totally Disconnected (non-metric) Gelfand Duality (2508.11188v1)

Abstract: We characterize those algebras over a disconnected uniformly complete topological field which are represenable as algebras of continuous functions on compact topologicla spaces, generalizing thus Gelfand duality for non-archimedean normed fields (Van der Put theorem). More generally, we establish for any topological field F a (dual) adjunction between the category of compact F-Tychonoff spaces and a natural category of commutative F-algebras, which becomes a duality for fields satisfying the Stone-Weierstrass theorem. To obtain these results we do not utilize analytic tools, but the canonical group uniformity of the field and intrinsic properties of the algebras.
