Anomalies of N = (4, 4) superconformal field theories coupled to a conformal supergravity background in two dimensions are computed by using the AdS/CFT correspondence. We find that Weyl, axial gauge and super Weyl transformations are anomalous, while general coordinate, local Lorentz, vector gauge and local super transformations are not. The coefficients of the anomalies show that the supercon...

This paper proposes a Maximum A Posteriori (MAP) algorithm for simultaneous disparity estimation and object segmentation using the stochastic diffusion. The stochastic diffusion is a new optimization method to search for the solutions in the MAP estimation, and is formulated to perform the simultaneous correspondence estimation and object segmentation using Markov random field models. A cluster...

The notion of homogeneous tensors is discussed. We show that there is a one-to-one correspondence between multivector fields on a manifold M , homogeneous with respect to a vector field ∆ on M , and first-order polydifferential operators on a closed submanifold N of codimension 1 such that ∆ is transversal to N . This correspondence relates the Schouten-Nijenhuis bracket of multivector fields o...
