Perturbative sigma models, elliptic cohomology and the Witten genus
Daniel Berwick-Evans
We provide a differential cocycle model for elliptic cohomology with complex coefficients and use analytic methods to construct a cocycle representative for the Witten class in thi…

The Chern-Gauss-Bonnet Theorem via supersymmetric Euclidean field theories
Daniel Berwick-Evans
We prove the Chern-Gauss-Bonnet Theorem using sigma models whose source supermanifolds have super dimension 0|2. Along the way we develop machinery for understanding manifold invar…
