Remarks on natural differential operators with tensor fields

Josef Janyška (2019)

Archivum Mathematicum

Similarity:

We study natural differential operators transforming two tensor fields into a tensor field. First, it is proved that all bilinear operators are of order one, and then we give the full classification of such operators in several concrete situations.

A Spectral Theory for Tensors

Edinah K. Gnang, Ahmed Elgammal, Vladimir Retakh (2011)

Annales de la faculté des sciences de Toulouse Mathématiques

Similarity:

In this paper we propose a general spectral theory for tensors. Our proposed factorization decomposes a tensor into a product of orthogonal and scaling tensors. At the same time, our factorization yields an expansion of a tensor as a summation of outer products of lower order tensors. Our proposed factorization shows the relationship between the eigen-objects and the generalised characteristic polynomials. Our framework is based on a consistent multilinear algebra which explains how...
