Hi.

I'm just a mathematics student. I don't plan to make any major edits or articles, I just want a place to have my small edits be counted up as random contributions.

Well, unless some major mathematical topic is missing.

Here's an outline before I start making the article later this week:

-Definition

-Representations --Examples of general representations --Least Absolute residues --Least Positive residues

-Some theorems

-Reduced residue classes

-Some theorems of this too

I still need someplace to mention the 'residue equivalence class' and the applications to group theory in this outline. Peter Stalin 14:13, 28 March 2007 (UTC)

Making a redirect Muller-Traub

I don't feel like doing this atm:

This linear algebra-related article is a stub. You can help Wikipedia by adding missing information.

In [linear algebra], a matrix ${\displaystyle A\in \mathbb {C} ^{n\times n}}$ has a displacement rank r if it satisfies a (Sylvester) displacement equation

${\displaystyle EA-AF=GH^{*}}$

Where ${\displaystyle G,H\in \mathbb {C} ^{n\times r}}$ and ${\displaystyle E,F}$ are called displacement matrices.

Such matrices are useful in defining and categorizing other structured matrices, for example, we can categorize the various matrix structures of the resultant matrix A by the following choices for E,F,G and H

Where ${\displaystyle g,h}$ are vectors, ${\displaystyle D_{t},D_{s}}$ are diagonal matrices,
