Tensor maths
The tensor algebra has two different coalgebra structures. One is compatible with the tensor product, and thus can be extended to a bialgebra, and can be further be extended with an antipode to a Hopf algebra structure. The other structure, although simpler, cannot be extended to a bialgebra. The first structure is developed immediately below; the second structure is given in the section on the cofree coalgebra, further down. WebTensor notation introduces one simple operational rule. It is to automatically sum any index appearing twice from 1 to 3. As such, \(a_i b_j\) is simply the product of two vector components, the i th component of the \({\bf a}\) vector with the j th component of the \({\bf b}\) vector. However, \(a_i b_i\) is a completely different animal because the subscript …

In mathematics, a tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space. Tensors may map between different objects such as vectors, scalars, and even other tensors. There are many types of tensors, including scalars and vectors … See more Although seemingly different, the various approaches to defining tensors describe the same geometric concept using different language and at different levels of abstraction. As multidimensional … See more Assuming a basis of a real vector space, e.g., a coordinate frame in the ambient space, a tensor can be represented as an organized multidimensional array of numerical values with respect to this specific basis. Changing the basis transforms the … See more There are several operations on tensors that again produce a tensor. The linear nature of tensor implies that two tensors of the same type may be added together, and that tensors … See more Tensor products of vector spaces The vector spaces of a tensor product need not be the same, and sometimes the elements of such a more general tensor product are called … See more An elementary example of a mapping describable as a tensor is the dot product, which maps two vectors to a scalar. A more complex example is the Cauchy stress tensor T, which takes a directional unit vector v as input and maps it to the stress vector T , … See more There are several notational systems that are used to describe tensors and perform calculations involving them.
