The Freed--Quinn line bundle from higher geometry
Daniel Berwick-Evans, Emily Cliff, Laura Murray
For a finite group , and level , Freed and Quinn construct a line bundle over the moduli space of -bundles on surfaces. Global sections determine the…
Elliptic cohomology and quantum field theory
Daniel Berwick-Evans
This survey provides an introduction to the Stolz-Teichner program on elliptic cohomology and quantum field theory.
Power operations preserve Thom classes in twisted equivariant Real K-theory
Daniel Berwick-Evans, Meng Guo
We construct power operations for twisted KR-theory of topological stacks. Standard algebraic properties of Clifford algebras imply that these power operations preserve universal T…
Averaging Property of Wedge Product and Naturality in Discrete Exterior Calculus
Mark D. Schubel, Daniel Berwick-Evans, Anil N. Hirani
In exterior calculus on smooth manifolds, the exterior derivative and wedge product are natural with respect to smooth maps between manifolds, that is, these operations commute wit…
The families analytic index for -dimensional Euclidean field theories
Daniel Berwick-Evans
We construct a -valued families index for a class of -dimensional Euclidean field theories. This realizes a conjectured cocycle map in the Stolz--Teichner program. W…
How do field theories detect the torsion in topological modular forms?
Daniel Berwick-Evans
We construct deformation invariants of -dimensional Euclidean field theories valued in a cohomology theory approximating topological modular forms. This implies several result…
