• Wednesday 14 November 2018 at UIC – Sebastian de Haro (Amsterdam): On Theoretical Equivalence and Duality
Abstract: Theoretical equivalence and duality are two closely related notions: but their interconnection has so far not been well understood. In this paper I explicate the contribution of a recent schema for duality to discussions of theoretical equivalence and physical equivalence. I argue that duality suggests a construal of theoretical equivalence for the physical sciences. The construal is in terms of the isomorphism of models, as defined by the Schema. I illustrate the construal in various formulations of Maxwell’s electromagnetic theory, and in electric-magnetic duality. In terms of technical difficulty, this talk rates 3/5
