The equivariant Chern character as super holonomy on loop stacks

Daniel Berwick-Evans, Fei Han

We study super parallel transport around super loops in a quotient stack, and show that this geometry constructs a global version of the equivariant Chern character.

Supersymmetric field theories and the elliptic index theorem with complex coefficients

Daniel Berwick-Evans

We present a cocycle model for elliptic cohomology with complex coefficients in which methods from 2-dimensional quantum field theory can be used to rigorously construct cocycles.…

Lie 2-algebras of vector fields

Daniel Berwick-Evans, Eugene Lerman

We show that the category of vector fields on a geometric stack has the structure of a Lie 2-algebra. This proves a conjecture of R.~Hepworth. The construction uses a Lie groupoid…
