Thermal stress tensor correlators, OPE and holography

Abstract In Faux Animal Head strongly coupled conformal field theories with a large central charge important light degrees of freedom are the stress tensor and its composites, multi-stress tensors.We consider the OPE expansion of two-point functions of the stress tensor in thermal and heavy states and focus on the contributions from the stress tens

Active Trace: A Sparse Spatiotemporal Representation for Videos

This paper proposes a sparse video representation with a deformable spatiotemporal template feature, named as active trace template.An active trace is the motion track of an active spatial feature, which moves in a certain velocity.To accommodate geometric variations of the spatial feature and motion variations of the temporal track, the atomic spa
