From SIAM News , Volume 37, Number 9, November 2004 Decomposing a **Tensor** By Misha Elena Kilmer and Carla D. Moravitz Martin Are there analogues to the SVD, LU, QR, and other matrix decompositions for **tensors** (i.e., higher-order or multiway arrays)?

**Tensors** You can’t walk across a room without using a **tensor** (the pressure **tensor**). You can’t align the wheels on your car without using a **tensor** (the inertia **tensor**).

There are two aspects of **tensors** that are of practical and fundamental importance: **tensor** notation and **tensor** invariance . **Tensor** notation is of great practical importance, since itsimplies handling of complex equation systems.

Vector and **Tensor** Mathematics 23 3.2 Vector and **Tensor** Mathematics The variables used to describe physical quantities are of an umber of types, including scalars, vectors, and **tensors**.

Introduction to **Tensors** Contravariant and covariant vectors Rotation in 2space: x' = cos x + sin y y' = sin x + cos y To facilitate generalization, replace (x, y) with (x 1 , x 2 ) Prototype contravariant vector: dr = (dx 1 , dx 2 ...

**TENSORS** (DRAFT COPY) LARRYSUSANKA Abstract. The purpose of this note is to define **tensors** with respect to a fixed finite dimensional real vector space and indicate what is being done when one performs common operations on **tensors**, such as contraction and raising or lowering indices.

**Tensors** For vector calculus Review •Vectors •Summation representation of annbynarray •Gradient, Divergence and Curl •Spherical Harmonics (maybe) Motivation If you tape a book shut and try to spin it in the air on each independent axis you will notice that it spins fine on two axes but ...
