Fully local Reshetikhin-Turaev theories
Daniel S. Freed, Claudia I. Scheimbauer, Constantin Teleman
Completing an arc of research initiated by Reshetikhin--Turaev and Witten, we construct fully local 3-dimensional topological field theories from non-degenerate braided fusion cate…
The role of p_1-structures in 3-dimensional Chern-Simons theories
Daniel S. Freed, Constantin Teleman
Our recent paper~\cite{FST} with Claudia Scheimbauer uses the cobordism hypothesis to construct fully local Chern-Simons theories. Here we expose some physics motivations: Yang-Mil…
The role of Coulomb branches in 2D gauge theory
Constantin Teleman
I give a simple construction of certain Coulomb branches of gauge theory in 3 and 4 dimensions defined by Nakajima et al. for a compact Lie group and a polarisab…
Integral Kirwan Surjectivity
Daniel Pomerleano, Constantin Teleman
We refine Kirwan's surjectivity and formality theorems for a Hamiltonian G-action on a compact symplectic manifold M. For a regular value of the moment map, we show that the Kirwan…
Discrete quantum systems from topological field theory
Daniel S. Freed, Michael J. Hopkins, Constantin Teleman
We introduce a technique to construct gapped lattice models using defects in topological field theory. We illustrate with 2+1 dimensional models, for example Chern-Simons theories.…
