The FZZ-Duality Conjecture - A Proof

Hikida, Yasuaki, Schomerus, Volker

Understand

We prove that the cigar conformal field theory is dual to the Sine-Liouville model, as conjectured originally by Fateev, Zamolodchikov and Zamolodchikov.

  • Since both models possess the same chiral algebra, our task is to show that correlations of all tachyon vertex operators agree.
  • We accomplish this goal through an off-critical version of the geometric Langlands duality for sl(2).
  • More explicitly, we combine the well-known self-duality of Liouville theory with an intriguing correspondence between the cigar and Liouville field theory.
