A Conjecture of Warnaar-Zudilin from Deformations of Lie Superalgebras
Thomas Creutzig, Niklas Garner
We prove a collection of -series identities conjectured by Warnaar and Zudilin and appearing in recent work with H. Kim in the context of superconformal field theory. Our proof…

Scattering off of Twistorial Line Defects
Niklas Garner, Natalie M. Paquette
The recently devised chiral algebra bootstrap computes the form factors of a special class of ``twistorial'' 4d QFTs as correlation functions of the theory's 2d celestial chiral al…

B-twisted Gaiotto-Witten theory and topological quantum field theory
Niklas Garner, Nathan Geer, Matthew B. Young
We develop representation theoretic techniques to construct three dimensional non-semisimple topological quantum field theories which model homologically truncated topological B-tw…
