Nicholas Teh (Notre Dame): 'Newton-Cartan theory as the philosopher's pleasure-dome'
In this talk, I will explore several philosophical themes that have recently emerged in the foundations of Newton-Cartan theory (a geometric non-relativistic theory of gravity), especially the status of the theory's "gauge symmetries", the role of symmetry-breaking observer fields in the theory, and the theory's relationship with teleparallel gravity. Part of the material will be based on joint work with Derek Wise and James Read (respectively).
