Curvature formula for the space of 2-d conformal field theories [PDF]
Daniel Friedan, Anatoly KonechnyWe derive a formula for the curvature tensor of the natural Riemannian metric on the space of two-dimensional conformal field theories and also a formula for the curvature tensor of the space of boundary conformal field theories.View original: http://arxiv.org/abs/1206.1749
