The ‘bridge‐building’ method
General explanation of the view of toposes as unifying spaces yielding ‘bridges’ between distinct mathematical theories: remarks on the existence of different sites of definition for a given topos and its logical interpretation, analysis of the representation theory of Grothendieck toposes and the problem of finding ‘elementary’ site characterizations for topos‐theoretic invariants.
La question est de savoir dans quel cas deux théories admettent le même topos classifiant.
