tensor calculus02 - tensor calculus tensor algebra02 - tensor calculustensorthe word tensor was introducedin 1846 by william rowan hamilton. it wasused in its current meaning by woldemarvoigt in 1899. tensor calculus was developed around 1890 by gregorio ricci-curbastro under the title absolute differentialcalculus. in the 20th century, the subjectcame to be known as tensor analysis, andachieved broader acceptance with the introduction of einsteins's theory of generalrelativity around 1915. tensors are usedalso in other fields such as continuummechanics.1tensor calculus - repetition2vector algebra - notation vector algebranotation, euklidian vector space, scalar product, vectorproduct, scalar triple product einstein‘s summation convention tensor algebranotation, scalar products, dyadic product, invariants, trace,determinant, inverse, spectral decomposition, sym-skewdecomposition, vol-dev decomposition, orthogonal tensor tensor analysisderivatives, gradient, divergence, laplace operator, integraltransformationstensor calculustensor calculus3 summation over any indices that appear twice in a termtensor calculus4

Tensor calculus on a 3-dimensional manifold only (3 1 formalism of general relativity) Main class: Tensor : stores tensor components with respect to a given triad and not abstract tensors Different metrics can be used at the same time (class Metric), with their associated covariant derivatives
on tensor decomposition, which aims to dissolve tensors into separable representations, while Song et al.(2019) reviewed tensor completion, which aims to impute the unobserved entries of a partially observed tensor. Tensor decomposition and tensor completion are both fundamen-tal problems i
tensor. Similarly, the vector is a rst order tensor, and a scalar is a zeroth order tensor. The order of the tensor equals the number of free indices (see SectionA.3) that the tensor has, and it can also be interpreted as the dimensionality of the array needed to represent the

Topics from Tensoral Calculus Jay R. Walton August 30, 2014 1 Preliminaries These notes are concerned with topics from tensoral calculus, i.e. generalizations of calculus to functions de ned between two tensor spaces. To make the discussion more concrete, the tensor spaces are de ned over ordinary Euclidean space, RN, with its usual inner product
