Smooth generalized symmetries of quantum field theories
Ben Gripaios, Oscar Randal-Williams, Joseph Tooby-Smith
Dynamical quantum field theories (QFTs), such as those in which spacetimes are equipped with a metric and/or a field in the form of a smooth map to a target manifold, can be formul…
The Alexander trick for homology spheres
Soren Galatius, Oscar Randal-Williams
We show that the group of homeomorphisms of a compact contractible -manifold which fix the boundary is contractible, as long as . We deduce this from a strong uniquene…
Monodromy and mapping class groups of 3-dimensional hypersurfaces
Oscar Randal-Williams
We describe the subgroup of the mapping class group of a hypersurface in consisting of those diffeomorphisms which can be realised by monodromy.
Configuration spaces as commutative monoids
Oscar Randal-Williams
After 1-point compactification, the collection of all unordered configuration spaces of a manifold admits a commutative multiplication by superposition of configurations. We explai…
On the cohomology of Torelli groups. II
Oscar Randal-Williams
We describe the ring structure of the rational cohomology of the Torelli groups of the manifolds in a stable range, for . Some of our results are a…
