Abstract: In this talk I will show how defining rules in a hypersequent setting can give a uniform proof-theoretic semantics of identity and modality, allowing – equally naturally – for (1) modal operators for which identity statements are necessary (if true), and (2) modal operators for which identity statements can be contingently true.
The talk is an online presentation for the ERC EXPRESS Project in Amsterdam, and the PHILMATH Seminar in Paris.
