Prelogarithmic operators and Jordan blocks in SL(2)ₖ affine algebra
Giribet, Gaston
Original · EN
The free field description of logarithmic and prelogarithmic operators in non compact Wess-Zumino-Witten model is analysed. We study the structure of the Jordan blocks of the SL(2)ₖ affine algebra and the role of the puncture operator in the theory in relation with the unitarity bound.
