Fusion rules and boundary conditions in the c=0 triplet model
The logarithmic triplet model W_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 W_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 W_2,3 only a subset of representations gives rise to consistent boundary
conditions. These then have boundary spectra with non-degenerate two-point
correlators.Comment: 50 pages; v2: changed formulation in section 1.2.1 and corrected

Minimal Model Holography
We review the duality relating 2d W_N minimal model CFTs, in a large N 't
Hooft like limit, to higher spin gravitational theories on AdS_3.Comment: 54 pages, 1 figure; Contribution to J. Phys. A special volume on
