  PlanetMath: monomial matrix
Obviously, a monomial matrix is a square matrix and there exists a rearrangement of rows and columns such that the result is a diagonal matrix.
A monomial matrix is invertible but, unlike a permutation matrix, not necessarily orthogonal.

  Monomial - Wikipedia, the free encyclopedia
The most obvious fact about monomials is that any polynomial is a linear combination of them, so they can serve as basis vectors in a vector space of polynomials - a fact of constant implicit use in mathematics.
In group representation theory, a monomial representation is a particular kind of induced representation.
In propositional logic, a monomial is a conjunction of literals.

 PlanetMath: monomial
First, the degree of a monomial is the sum of the elements of its vector representation.
If a polynomial is represented as a sum over a set of monomials, then the degree of a polynomial can be defined as the degree of the monomial of largest degree belonging to that polynomial.

 Monomial basis - Wikipedia, the free encyclopedia
In mathematics a monomial basis is a way to uniquely describe a polynomial using a linear combination of monomials.
This description, the monomial form of a polynomial, is often used because of the simple structure of the monomial basis.

 Representation and Monomial Orders
Multivariate polynomial rings are constructed in Magma such that the monomials of any polynomial are sorted with respect to a specified monomial order, with the greatest monomial first.
The order is called "graded reverse lexicographical" since it first grades the monomials by total degree, and then decides ties by the negation of the lexicographical order applied to the variables in reverse order.
The order is called "univariate" since when monomials are compared, any monomial not containing the i-th variable is greater than any monomial containing the i-th variable.

 Monomial Representations for Gröbner Bases Computations
Monomial representations and operations for Gröbner bases computations are investigated from an implementation point of view.
The technique of vectorized monomial operations is introduced and it is shown how it expedites computations of Gröbner bases.
Furthermore, a rank-based monomial representation and comparison technique is examined and it is concluded that this technique does not yield an additional speedup over vectorized comparisons.

 Automatic Generation of Transform Algorithms
The approach extends the well known concept of discrete Fourier transforms over finite groups and became feasible through two advances: A method to decompose monomial representations of solvable groups by structural recursion and a method to compute certain symmetries of matrices by combinatorial search.
The methods have been implemented in the library AREP and used to generate fast algorithms for a class of transforms including the discrete Fourier, cosine, sine, and Hartley transform, automatically.
We present an efficient algorithm which decomposes a monomial representation of a solvable group G into its irreducible components.

 Monomial Orders
The order is called "univariate" since monomials are compared so that any monomial not containing the i-th variable is greater than any monomial containing the i-th variable.
Thus all variables but the i-th are "eliminated" so that a Gröbner basis of an ideal I with this ordering will contain the unique monic generator of the elimination ideal consisting of all the polynomials in I containing the i-th variable alone.
The order is specified by the arguments ("weight", Q) where Q is a sequence of n^2 non-negative integers or rationals describing the n weight vectors of length n (in row major order).

The effect of this response is that the higher the component, or row, number, the greater the monomial.

For column vectors this is not possible, since the lead monomial can occur in any row.

 Monomial orderings
As you will discover using the Groebner applet, different monomial orderings not only lead to different Groebner bases for the same ideal, but they also affect substantially the computation.
Since a polynomial is a linear combination of monomials, we would like to rearrange unambiguously the terms in a polynomial in descending (or ascending) order.
The lex order is useful when we need to eliminate the variables in solving systems of equations, but when we only want to eliminate certain variables and we do not care about the others, we can use the more efficient k-th elimination order.

 Monomial orders
If their total degrees are not equal, then the monomial with the smaller total degree is considered smaller in the graded lex order.
Also two monic monomials containing b are ranked by first comparing the number of occurrences of the variable b in the monomial.
are monic monomials in a and c (or in a and d or in b and c or in b and d), then they are ordered by the pure lex order a « c (or a « d or b « c or b « d).

 Greatest monomial factor level1
Now you know that monomials can be broken down into their various factors, and this is called "factoring monomials".
Find the greatest common monomial factor of this polynomial, divide it out, and rewrite the polynomial as a multiplication problem using the factors you found
Try these using the same technique as the one variable, greatest common monomial factoring.

We could of course extract the leading monomial from a polynomial each time we needed it, but it's faster to do it this way, since Spoly and the division routines are such that they only require the leading terms.

It is well known that the integral closure of a monomial ideal in a polynomial ring in a finite number of indeterminates over a field is a monomial ideal, again.
An ideal $\mathfrak a$ of $R$ is called a monomial ideal with respect to $(x_1,\ldots,x_d)$ if it can be generated by monomials $x_1^{i_1}\cdots x_d^{i_d}$.

The main contribution of this paper is that an earlier decomposition method from Larsen for the De Simone format is extended to the more general ntyft/ntyxt format without lookahead.
The only known extension to additives, based on monomial weights, fails to preserve this key feature: a host of cut-free monomial proof nets can correspond to the same cut-free proof.
Thus the problem of finding a satisfactory notion of proof net for unit-free multiplicative-additive linear logic (MALL) has remained open since the inception of linear logic in 1986.
