Conditions for Theoretical Equivalence, Duality, and Implications Thereof — •Konner Childers — University of Birmingham, UK

Recent attention in philosophy of physics literature has been directed towards dualities between physical theories, furthering the *theoretical equivalence* questions into a new domain. After re-introducing the distinction between theoretical equivalence and dualities, this paper shall seek to critically assess 1) the sense in which dualities are (not) equivalences, with special attention given to categorical and physical equivalence, 2) the role of semantics and reference in addressing duality relations between theories, and 3) issues regarding the criteria of empirical (in)equivalence and predictions with respect to T-duality and gauge/gravity duality. Finally, these results shall be applied to fermionic particle-vortex and recently proposed 3d bosonization dualities to both elucidate the formal and empirical relations and to suggest further avenues for research.
