Sophistication about symmetries

Dewar, Neil (11. September 2017): Sophistication about symmetries. In: The British Journal for the Philosophy of Science

Abstract

Suppose that one thinks that certain symmetries of a theory reveal “surplus structure”. What would a formalism without that surplus structure look like? The conventional answer is that it would be a reduced theory: a theory which traffics only in structures invariant under the relevant symmetry. In this paper, I argue that there is a neglected alternative: one can work with a sophisticated version of the theory, in which the symmetries act as isomorphisms.
