I shall speak about some recent developments on the subject of modal model theory for the Junior Logic Seminar at the University of Oxford. The talk, titled The Mathematical Multiverse, will take place at the Mathematical Institute on November 16, 2021 at 5PM UK time. Please contact Brian Tyrrell should you like to join us.
Abstract. Expanding on the subject of modal model theory introduced by Joel David Hamkins and myself, I should like to share some progress on the quest to unearth the modal nature of mathematics.
