MCMP – Philosophy of MathematicsThe Univalence AxiomSteve Awodey (CMU) gives a talk at the MCMP Colloquium (16 July, 2014) titled "The Univalence Axiom". Abstract: In homotopy type theory, the Univalence Axiom is a new principle of reasoning which implies that isomorphic structures can be identified. I will explain this axiom and consider its background and consequences, both mathematical and philosophical.

Abstract: Recent advances in foundations of mathematics have led to some developments that are significant for the philosophy of mathematics, particularly structuralism. The discovery of an interpretation of constructive type theory into homotopy theory suggests a new approach to the foundations of mathematics with both intrinsic geometric content and a computational implementation. In this setting, leading homotopy theorist Vladimir Voevodsky has proposed new axiom for foundations with both geometric and logical significance: the Univalence Axiom. It captures the familiar...
