Symmetric tensor product
In mathematics, a symmetric tensor is a tensor that is invariant under a permutation of its vector arguments: $${\displaystyle T(v_{1},v_{2},\ldots ,v_{r})=T(v_{\sigma 1},v_{\sigma 2},\ldots ,v_{\sigma r})}$$for every permutation σ of the symbols {1, 2, ..., r}. Alternatively, a symmetric tensor of order r represented in … See more If T is a simple tensor, given as a pure tensor product $${\displaystyle T=v_{1}\otimes v_{2}\otimes \cdots \otimes v_{r}}$$ then the symmetric part of T is the symmetric product … See more • Antisymmetric tensor • Ricci calculus • Schur polynomial • Symmetric polynomial See more • Cesar O. Aguilar, The Dimension of Symmetric k-tensors See more In analogy with the theory of symmetric matrices, a (real) symmetric tensor of order 2 can be "diagonalized". More precisely, for any tensor T ∈ Sym (V), there is an integer r, non-zero unit vectors v1,...,vr ∈ V and weights λ1,...,λr such that See more 1. ^ Carmo, Manfredo Perdigão do (1992).

An idea I just had would be something like \renewcommand {\tensor} {\ensuremath\otimes\limits} but it does not work because \otimes is not a math operator. you could then try \mathop {\opotimes} {$\otimes$} (i've forgotten which code …

WebIn this paper, we define the semi-symmetric metric connection on super Rie-mannian manifolds. We compute the semi-symmetric metric connection and its curva-ture tensor and its Ricci tensor on super warped product spaces. We introduce two kind of super warped product spaces with the semi-symmetric metric connection and give the The tensor product of two vector spaces is a vector space that is defined up to an isomorphism. There are several equivalent ways to define it. Most consist of defining explicitly a vector space that is called a tensor product, and, generally, the equivalence proof results almost immediately from the basic properties of the vector spaces that are so defined. The tensor product can also be defined through a universal property; see § Universal property, be…
