Chris Fields: "What is the Identity operator?" 

Topos Institute Colloquium, 19th of September 2024.
---
The idea that objects have associated Identity morphisms, or operators, is fundamental to mathematics, physics, and the theory of Active Inference. All of these, moreover, support the idea that identity can be maintained via multiple paths. We will explore the relationship between the idea of identity and the notions of space, time, and memory, with an emphasis on how these latter three relate to the idea of an object in both physical theory and active inference.
