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…
Flat principal 2-group bundles and flat string structures
Daniel Berwick-Evans, Emily Cliff, Laura Murray +2
For a weak 2-group, we construct a bicategory of flat 2-group bundles over differentiable stacks as a localization of a functor bicategory. This description is amenable to explicit…
Chiral algebras, factorization algebras, and Borcherds's "singular commutative rings" approach to vertex algebras
Emily Cliff
We recall Borcherds's approach to vertex algebras via "singular commutative rings", and introduce new examples of his constructions which we compare to vertex algebras, chiral alge…
On the Kirwan map for moduli of Higgs bundles
Emily Cliff, Thomas Nevins, Shiyu Shen
Let be a smooth complex projective curve and a connected complex reductive group. We prove that if the center of is disconnected, then the Kirwan map $H^*\big(\o…
Universal factorization spaces and algebras
Emily Cliff
We introduce categories of weak factorization algebras and factorization spaces, and prove that they are equivalent to the categories of ordinary factorization algebras and spaces,…
Universal D-modules and stacks of étale germs of n-dimensional varieties
Emily Cliff
We introduce stacks classifying étale germs of pointed n-dimensional varieties. We show that quasi-coherent sheaves on these stacks are universal D- and O-modules. We state and pro…
