On a categorical structure of the set of all CFTs
Rotem Ben Zeev, Behzat Ergun, Elisa Milan +1
We identify a categorical structure of the set of all CFTs. In particular, we show that the set of all CFTs has a natural monoidal strict -category structure with the -morphi…
Nonabelian Twists of the Theory
Jacques Distler, Behzat Ergun, Ali Shehper
We study theories of type in class-S, with nonabelian outer-automorphism twists around various cycles of the punctured Riemann surface . We propose an extension of previou…
Distinquishing 4d N=2 SCFTs
Jacques Distler, Behzat Ergun, Ali Shehper
We construct a family of examples of pairs of 4d N=2 SCFTs whose graded Coulomb branch dimensions, Weyl-anomaly coefficients and flavour symmetry algebras and levels coincide, but…
Factorized class theories and surface defects
Behzat Ergun, Qianyu Hao, Andrew Neitzke +1
It is known that some theories of class are actually factorized into multiple decoupled nontrivial four-dimensional theories. We propose a way of constructing examples of…
Product SCFTs for the Theory
Jacques Distler, Behzat Ergun
We present a simple criterion for when an N=2 SCFT must be a product SCFT. Applied to the class-S theories of type , we find 29 (out of 11,000) 3-punctured spheres which are p…
Product SCFTs in Class-S
Jacques Distler, Behzat Ergun, Fei Yan
We develop a technique for counting the number of stress tensor multiplets in a 4D SCFT. This provides a simple diagnostic for when an isolated (non-Lagrangian) SCF…
