Abstract

The logarithmic triplet model \Wc_{2,3} at c = 0 is studied. In particular, we determine the fusion rules of the irreducible representations from first principles and show that there exists a finite set of representations, including all irreducible representations, that closes under fusion. With the help of these results, we then investigate the possible boundary conditions of the \Wc_{2,3} theory. Unlike the familiar Cardy case where there is a consistent boundary condition for every representation of the chiral algebra, we find that for \Wc_{2,3} only a subset of representations gives rise to consistent boundary conditions. These then have boundary spectra with non-degenerate two-point correlators.
