Topic: Multilinear form


  
  Multilinear map - Wikipedia, the free encyclopedia
In linear algebra, a multilinear map is a mathematical function of several vector variables that is linear in each variable.
The determinant of a matrix is a skew-symmetric multilinear function of the columns (or rows) of a square matrix.
The trace of a matrix is a multilinear function of the columns (or rows) of a square matrix.

 NSDL Metadata Record -- Alternating Multilinear Form -- from MathWorld
An alternating multilinear form on a real vector space V is a multilinear form F:V \otimes \cdots \otimes V \rightarrow \mathbb{R} such that F(x_1, \dots, x_i, x_{i+1}, \dots, x_n) = -F(x_1, \dots, x_{i+1}, x_i, \dots, x_n) for any index i.
For example, F((a_1,a_2,a_3),(b_1,b_2,b_3),(c_1,c_2,c_3))= a_1 b_2 c_3 -a_1 b_3 c_2 +a_2 b_3 c_1 - a_2 b_1 c_3 + a_3 b_1 c_2 - a_3 b_2 c_1 (3) is an alternating form on \mathbb{R}^3.
An alternating multilinear form is defined on a module in a similar...

In this way, we can define the integral of a form over a linear combination of manifolds to be the very same linear combination of integrals of the same form over the manifolds.
Here we extend this situation to forms whose coefficients are rational multiples of the same holonomic sequence, and make the link between closed forms and creative telescoping explicit.

 Grant-funded Project Nr. 269/2001/B-MAT/MFF - Final Report   (Site not responding. Last check: 2007-10-10)
Trilinear forms: Jan Hora in his paper "Orthogonal decompositions and canonical embeddings of multilinear alternating forms" (published in Linear and Multinear Algebra), proves that for every k-linear form, with k at least 3, one can find exactly one finest orthgonal decomposition.
At the same time Hora proves that every nondegenerate multilinear alternating form can be obtained as a form acting on a vector subspace of a form that is a power of a determinate (considered as a multilinear form).
Trilinear forms appear also in the result of T. Kepka (together with P. Němec a D. Herbera), in which there comes to a summit a long-term effort to find a nonmedial distributive hamiltonian quasigroup.

 One-Forms
But in general, the gradient of a function is naturally a one-form: its purpose in life is to take a vector and spit out the value of the directional derivative in that direction -- this value doesn't depend on the inner-product (metric) you're using...
This is true in general -- in coordinates, one-forms are supposed to be written as 1xn matrices, while vectors are as nx1 matrices.
One yellow-and-white book which I have says that a natural extension of the concept of a bilinear form on a vector space is a multilinear form.

 Tail Probabilities of the Maxima of Multilinear Forms and Their Applications
For qi-dimensional vector hi, i=1,...., k, define a multilinear form of degree k by (h1 x hk)'vec(Z).
We derive formulas for upper tail probabilities of the maximum of multilinear form with respect to hi's under the condition hi=1 for any i, and of its standardized statistic obtained by dividing by vec(Z).
We also give formulas for the maximum of symmetric multilinear form (h1 x...x hk)'vec(sym(Z)),@where sym(Z) denotes the symmetrization of Z with respect to indices.

The memex has been realized in digital form as the World Wide Web, but what Bush conceived of as a method of forming private trails of texts for future reference has become instead a mode of public communication.
Multilinearity: Theorists have pointed out that "nonlinear" does not adequately describe reading of any kind because letters and words are parsed sequentially regardless of the length of the textual chunk.

 Literature in a Hypermedia Mode: An interview with Marjorie Luesebrink | PopMatters Artists and Innovators Series
One subset of electronic literature is "hypertextual" — that is, literature which is characterized by mulitple links from pages or sections, multilinear structures, and a spatial or temporal organization.
Hypermedia literature usually has a multilinear form, but also uses graphics, sound, animation, or video as part of the content.
Some individuals are interested in electronic forms (Oakley Hall arranged for readings from Califia at the Squaw Valley Writer's Conference, for example), but until hypermedia is accepted by critics and literature teachers, many new writers are reluctant to take the risk and invest the time to enter the field.

 FEniCS :: FFC
FFC functions as the form evaluation system for DOLFIN but can also be used to compile forms for other systems.
FFC works as a compiler for multilinear forms by generating code (C or C++) for the evaluation of a multilinear form given in mathematical notation.
This new approach to form evaluation makes it possible to combine generality with efficency; the form can be given in mathematical notation and the generated code is as efficient as hand-optimized code.

In the accompanying diagram the reader might observe a few clusters of related fields, showing both the many parts of linear algebra and the related fields in which many of these themes are extended and applied.
Also crowded near the center of the diagram are several fields concerned with linear spaces and linear transformations, and in some cases the reflection of those ideas in the corresponding matrices.
Sets of matrices qua sets arise geometrically as well; for example certain families of matrices form manifolds, and even topological groups (22).

 Spencer - The Work - Evolution--Unilinear or Multilinear   (Site not responding. Last check: 2007-10-10)
In many passages Spencer expresses what seems to be a belief in the unilinear evolution of mankind, in which it appears that mankind's progress through stages of development is as rigidly determined as the evolution of individuals from childhood to maturity.
The process cannot be abridged and must be gone through with due patience." At times, especially in his earlier writings, Spencer pictures the process of evolution as unremitting, unrelenting, and ever present.
Although passages to the contrary could be quoted, Spencer by and large believed that societies do not develop irreversibly through predetermined stages.

The edges will be labeled (or "colored" as they sometimes say) with representations of the group and the nodes will be labeled with multilinear forms on the representation spaces.
The edges disappear as their operators apply themselves to the multilinear forms---producing new multilinear forms---and the nodes disappear as those are eaten in turn by other operators.
