  NationMaster - Encyclopedia: Finitely generated module
Thus we say that the whole area of the map is generated by the set {1 mile east, 1 mile north} together with coefficients from the real numbers.
In the case where the module M is a vector space over a field R, and the generating set is linearly independent, n is well-defined and is referred to as the dimension of M (well-defined means that any linearly independent generating set has n elements: this is the dimension theorem for vector spaces).
However, for a general ring R, it is an important concept, as is evidenced by the fact that the category of all finitely presented R-modules is abelian, something that's not generally true for the category of all finitely-generated R-modules.

 General Form of an Estimable Function
If other generating sets for L are represented symbolically, the symbolic notation looks different.
With the thousands of generating sets available, the question arises as to which one is the best to represent L symbolically.
Clearly, a generating set containing a minimum of rows (of full row rank) and a maximum of zero elements is desirable.

D' is a free set that spans M. Such a minimal generating set of M is called a BASIS of M. In this introduction, we restrict the theory to vector spaces with a finite basis.
The space generated by D is called the row space of A. The rows of A are a generating set of the row space.
The space generated by D is called the column space of A. The columns of A are a generating set of the column space.

 ipedia.com: Generating set of a group Article   (Site not responding. Last check: )
In abstract algebra, a generating set of a group is a subset S of a group G, such that every element of G can be expressed as the product of finitely many elements of S and their inverses.
More generally, if S is a subset of a group G, then is the smallest subgroup of G containing every element of S; equivalently, is the subgroup of all elements of G that can be expressed as the finite product of elements in S and their inverses.
The most general group generated by a set S is the group freely generated by S. Every group generated by S is isomorphic to a factor group of this group; a feature which is utilized in the expression of a group's presentation.

 4.5 Generating set for the module of syzygies
These generators do not form a minimal set and there are relations between them; in fact this method does not guarantee a minimum set of generators.
Therefore, from this proven set of generators we can check whether a particular set is in fact a generating set.
Another set of generators which may be useful for further work is a Gröbner basis of a module.

 Generating set - Wikipedia, the free encyclopedia
In mathematics, generating set refers to several related concepts:
Generating set of a group: S is a generating set of a group if the smallest subgroup of G containing S is G itself.
For example, polynomials are a generating set of the space of all continuous functions on the closed unit interval, because taking closure under limits forms the entire space.

Section 2 outlines general requirements for the installation of generating sets and Sections 3 and 4 introduce additional requirements for permanently connected and plug and socket-outlet connected generating sets respectively.

 OERC - Case No 2 of 1996
Subsequently, the rating of the proposed generating set was stated to be 380 KVA and finally it has been indicated that it is of 365 KVA.
It is thus clear that the petitioner has installed a generating set of higher rating than what needed by his contracted load and distinctive requirements of the load profile.
We have noted earlier that the petitioner has established a generating set with a higher rating costing more money, thus enabling him to draw higher subsidy from the Industry Department than what he would have been entitled to in case he had established a generating set of lower rating.

 Generating Sets for the Knapsack Problem   (Site not responding. Last check: )
This talk deals with the study of generating sets for the set of all non-neagtive integer solutions of a linear diophantine equation.
Such a generating set is a subset of integral vectors such that every difference vector of two integer points that satisfy the linear diophantine equation can be written as the non-negative integer combination of elements from the generating set.
A generating set for a linear diophantine equation also defines a test set for the knapsack problem.

 Finding a small generating set for an ideal
Determining an algorithm for finding a minimal length generating set for an ideal is an open problem for commutative polynomial rings and is probably unsolvable in the noncommutative case.
A more practical goal is to try to find, given a finite set X of polynomials, a minimal generating subset of X (that is, a subset Y of X which generates the same ideal which X generates and which is a minimal generating set).
Thus, from a purely mathematical point of view, one natural generalization of a commutative reduced Gröbner Basis is a minimal generating subset of a reduced Gröbner Basis (even though this minimal generating subset is not itself a GB).

However, it was accepted that the statement in the standard is not clear and could easily be interpreted to mean, for example, generating sets that are available for hire.
Assuming that the technical developments that have been associated with present day generating sets continues at the same level over the next five years, we should see some remarkable results and long-term benefits to human health.
