WebA symmetric tensor is a higher order generalization of a symmetric matrix. In this paper, we study various properties of symmetric tensors in relation to a decomposition into a symmetric sum of outer product of vectors. A rank-1 order- k tensor is the outer product of k nonzero vectors. Any symmetric tensor can be decomposed into a linear ...

Let (A, ⊗) be a symmetric ribbon fusion category over C.It is well-known [17] that its Drinfeld centre Z (A) is a modular tensor category, with tensor product ⊗ c.By Tannaka duality [7], there is a finite group or supergroup G, such that A ≅ Rep (G).With this identification, we have another description [5, Chapter 3.2] of the Drinfeld centre as …
