Hermitian tensor decompositions
WitrynaA rank-1 Hermitian tensor must have form [v1;v2; ;vm] h:= v1 v2 vm v1 v2 vm: Every Hermitian tensor is a sum of rank-1 Hermitian tensors. The smallest such length is … WitrynaConsidering M being a complex n − dimensional manifold, the tangent bundle T M to M can be seen as a holomorphic vector bundle. In fact, if we consider T M C := T M ⊗ R C then it splits as. T M C = T M ′ ⊕ T M ″, where the spaces on the decomposition are the eigenspaces associated to the extension to T M C of the standard complex ...
