Line Operators in 3d Holomorphic QFT: Meromorphic Tensor Categories and dg-Shifted Yangians
Tudor Dimofte, Wenjun Niu, Victor Py
We study line operators and their OPE's in perturbative 3d holomorphic-topological QFT's, including holomorphic-topological twists (quarter-BPS sectors) of 3d theories. In pa…
Tannakian QFT: from spark algebras to quantum groups
Tudor Dimofte, Wenjun Niu
We propose a nonperturbative construction of Hopf algebras that represent categories of line operators in topological quantum field theory, in terms of semi-extended operators (spa…
3d mirror symmetry of braided tensor categories
Andrew Ballin, Thomas Creutzig, Tudor Dimofte +1
We study the braided tensor structure of line operators in the topological A and B twists of abelian 3d gauge theories, as accessed via boundary vertex operator alg…
A QFT for non-semisimple TQFT
Thomas Creutzig, Tudor Dimofte, Niklas Garner +1
We construct a family of 3d quantum field theories that conjecturally provide a physical realization -- and derived generalization -- of non-semisimple mathema…
Boundary Chiral Algebras and Holomorphic Twists
Kevin Costello, Tudor Dimofte, Davide Gaiotto
We study the holomorphic twist of 3d gauge theories in the presence of boundaries, and the algebraic structure of bulk and boundary local operators. In the holomorphic…
Mirror symmetry and line operators
Tudor Dimofte, Niklas Garner, Michael Geracie +1
We study half-BPS line operators in 3d N=4 gauge theories, focusing in particular on the algebras of local operators at their junctions. It is known that there are two basic types…
