In multilinear algebra, a tensor contraction is an operation on a tensor that arises from the natural pairing of a finite-dimensional vector space and its dual. In components, it is expressed as a sum of products of scalar components of the tensor(s) caused by applying the summation convention to a pair … See more Let V be a vector space over a field k. The core of the contraction operation, and the simplest case, is the natural pairing of V with its dual vector space V . The pairing is the linear transformation from the tensor product of … See more As in the previous example, contraction on a pair of indices that are either both contravariant or both covariant is not possible in general. … See more One can generalize the core contraction operation (vector with dual vector) in a slightly different way, by considering a pair of tensors T and U. The tensor product In tensor index … See more • Tensor product • Partial trace • Interior product • Raising and lowering indices See more In tensor index notation, the basic contraction of a vector and a dual vector is denoted by $${\displaystyle {\tilde {f}}({\vec {v}})=f_{\gamma }v^{\gamma }}$$ which is shorthand for the explicit coordinate summation See more Contraction is often applied to tensor fields over spaces (e.g. Euclidean space, manifolds, or schemes ). Since contraction is a purely algebraic operation, it can be applied pointwise to a tensor field, e.g. if T is a (1,1) tensor field on Euclidean space, then in any … See more Let R be a commutative ring and let M be a finite free module over R.

In operator theory, a bounded operator T: X → Y between normed vector spaces X and Y is said to be a contraction if its operator norm T ≤ 1. This notion is a special case of the concept of a contraction mapping, but every bounded operator becomes a contraction after suitable scaling. The analysis of contractions provides insight into the structure of operators, or a family of operators. The theory of contractions on Hilbert space is largely due to Béla Szőkefalvi-Nagy and Ciprian … WebApr 2, 2013 · The "double inner product" and "double dot product" are referring to the same thing- a double contraction over the last two indices of the first tensor and the first two indices of the second tensor.
