TFT construction of RCFT correlators IV: Structure constants and correlation functions
Jürgen Fuchs, Ingo Runkel, Christoph Schweigert
We compute the fundamental correlation functions in two-dimensional rational conformal field theory, from which all other correlators can be obtained by sewing: the correlators of…
Kramers-Wannier duality from conformal defects
J"urg Fr"ohlich, J"urgen Fuchs, Ingo Runkel +1
We demonstrate that the fusion algebra of conformal defects of a two-dimensional conformal field theory contains information about the internal symmetries of the theory and allows…
TFT construction of RCFT correlators III: Simple currents
Juergen Fuchs, Ingo Runkel, Christoph Schweigert
We use simple currents to construct symmetric special Frobenius algebras in modular tensor categories. We classify such simple current type algebras with the help of abelian group…
