Large-c conformal (n ≤ 6)-point blocks with superlight weights and holographic Steiner trees
Abstract
In this note we study CFT2 Virasoro conformal blocks with heavy operators in the large-c limit in the context of AdS3/CFT2 correspondence. We compute the lengths of the holographic Steiner trees dual to the 5-point and 6-point conformal blocks using the superlight approximation when one or more dimensions are much less than the others. These results are generalized for N-point holographic Steiner trees dual to (N+1)-point conformal blocks with superlight weights.
