I guess you don't understand category theoretical stuff... OK. Section 6.3 and 6.4 are very nice formal treatments of the idea that I am exploring, the Stone duality thing that I am often sputtering on and on about. ;-) My idea is that Boolean algebras can evolve via non-exact homomorphsims. ;-) I just don't happen to think or write in formal terms. Brent Original Message Subject:[FOM] Preprint: Topological Galois Theory Date: Thu, 3 Jan 2013 20:08:04 +0100 From: Olivia Caramello oc...@hermes.cam.ac.uk Reply-To: Foundations of Mathematics f...@cs.nyu.edu To: Foundations of Mathematics f...@cs.nyu.edu Dear All, The following preprint is available from the Mathematics ArXiv at the addresshttp://arxiv.org/abs/1301.0300 : O. Caramello, Topological Galois Theory Abstract: We introduce an abstract topos-theoretic framework for building Galois-type theories in a variety of different mathematical contexts; such theories are obtained from representations of certain atomic two-valued toposes as toposes of continuous actions of a topological group. Our framework subsumes in particular Grothendieck's Galois theory and allows to build Galois-type equivalences in new contexts, such as for example graph theory and finite group theory. This work represents a concrete implementation of the abstract methodologies introduced in the paper The unification of Mathematics via Topos Theory, which was advertised on this list two years ago. Other recent papers of mine applying the same general principles in other fields are available for download at the addresshttp://www.oliviacaramello.com/Papers/Papers.htm .
