Spin, Statistics and SPASs — •Christopher Fewster — Department of Mathematics, University of York, York, U.K.

Many of the main problems in quantum field theory in curved spacetime (QFT in CST) stem from the fact that there is, in general, no (nontrivial) replacement for the Poincaré symmetry group. Because Poincaré symmetry is at the root of many of the main structural features of QFT in Minkowski space, such as the spin-statistics connection, axiomatic approaches to QFT in CST have been under-developed until fairly recently.

In this talk, I describe some recent progress in the locally covariant framework for QFT in curved spacetimes, taking the spin-statistics connection as the main example. I will also discuss how the framework allows one to pose and partly resolve the issue of whether a given theory can be said to describe the Same Physics in All Spacetimes (SPASs).
