Relative tensor calculus and the tensor time derivative

Foundations of Physics, 1974
A relative tensor calculus is formulated for expressing equations of mathematical physics. A tensor time derivative operator ▽ b a is defined which operates on tensors λia...ib. Equations are written in a rigid, flat, inertial or other coordinate system a, altered to relative tensor notation, and are thereby expressed in general flowing coordinate ...

Tensor induction of relative syzygies

Journal für die reine und angewandte Mathematik (Crelles Journal), 2000
Let \(\mathcal O\) be a complete Noetherian local ring with residue field \(k\) of characteristic \(p>0\), and \(P\) a \(p\)-group. An \(\mathcal O\)-algebra of the form \(A=\text{End}_{\mathcal O}(M)\), where \(M\) is an endopermutation \({\mathcal O}P\)-lattice having an indecomposable direct summand with vertex \(P\), is called a Dade \(P\)-algebra.

Tensor-based keypoint detection and switching regression model for relative radiometric normalization of bitemporal multispectral images

International Journal of Remote Sensing, 2022
In some remote sensing applications, such as unsupervised change detection, bitemporal multispectral images must be first aligned/harmonized radiometrically.

The relative deformation tensor for small displacements in general relativity

General Relativity and Gravitation, 1989
By means of the world-function, an approximate formula for the relative deformation tensor of an elastic continuum in a space-time of finite curvature is obtained. The coordinate displacements are supposed to be small with respect to the characteristic measure of the geodesic joining an arbitrary point of that continuum and a fixed point of the space ...
