Freefield representation of permutation branes in Gepner models
Abstract
We consider freefield realization of Gepner models basing on freefield realization of N=2 superconformal minimal models. Using this realization we analyse A/Btype boundary conditions starting from the ansatz when leftmoving and rightmoving freefields degrees of freedom are glued at the boundary by an arbitrary constant matrix. It is shown that the only boundary conditions consistent with the singular vectors structure of unitary minimal models representations are given by permutation matrices and give thereby explicit freefield construction of permutation branes of Recknagel.
