# Global anomalies on physical space-times

Alexander Schenkel, Jochen Zahn
September 21, 2016
We formulate an algebraic criterion for the presence of global anomalies on globally hyperbolic space-times in the framework of locally covariant field theory. We discuss some consequences and check that it reproduces the well-known global $SU(2)$ anomaly in four space-time dimensions.
