Compact formula for conserved three-point tensor structures in 4D CFT
What the study found The study found a compact analytic formula for a complete basis of conformally invariant tensor structures for three-point functions of conserved operators in four-dimensional conformal field theory (CFT). It also found that the same framework can be used for cases with one non-conserved operator. Why the authors say this matters The…
Non-Gaussian redshift-space Minkowski tensors show qualified perturbation-theory success
What the study found The study found that perturbation-theory predictions for Minkowski tensors in redshift space are a qualified success when compared with dark matter simulation measurements. It also found that nonperturbative Finger-of-God effects remain significant at relatively large scales, especially in components parallel to the line of sight. Why the authors say this matters…
Tensor nuclear norm is fully decomposable on specific subspaces
—
in MathematicsWhat the study found The study shows that the tensor nuclear norm can be fully decomposed over specific subspaces, and it identifies the largest subspaces for which this full decomposability holds. It also derives new inclusions for the subdifferential, which is the set of all valid subgradients, of the tensor nuclear norm. Why the authors…
