Example types with submodule
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
If N has a non-zero proper submodule, then this process can be repeated. (14 words)
More generally, it is true that every nonzero finitely generated module has a maximal submodule. (15 words)
If M is a free module over a principal ideal domain R, then every submodule of M is again free. (20 words)
If I is a right ideal of R, then I is simple as a right module if and only if I is a minimal non-zero right ideal: If M is a non-zero proper submodule of I, then it is also a right ideal, so I is not minimal. (50 words)
For instance, if U is right R-module, and V is a maximal submodule of U, U·J(R) is contained in V, where U·J(R) denotes all products of elements of J(R) (the "scalars") with elements in U, on the right. (44 words)
The notion of ideal generalises to any Mal'cev algebra (as linear subspace in the case of vector spaces, normal subgroup in the case of groups, two-sided ideals in the case of rings, and submodule in the case of modules ). (41 words)
Example sentences (9)
A submodule N of M is a direct summand of M if there exists some other submodule N′ of M such that M is the internal direct sum of N and N′.
Conversely, if I is not minimal, then there is a non-zero right ideal J properly contained in I. J is a right submodule of I, so I is not simple.
For instance, if U is right R-module, and V is a maximal submodule of U, U·J(R) is contained in V, where U·J(R) denotes all products of elements of J(R) (the "scalars") with elements in U, on the right.
If I is a right ideal of R, then I is simple as a right module if and only if I is a minimal non-zero right ideal: If M is a non-zero proper submodule of I, then it is also a right ideal, so I is not minimal.
If M is a free module over a principal ideal domain R, then every submodule of M is again free.
If N has a non-zero proper submodule, then this process can be repeated.
If X is a non-zero module over a ring R and the action of G is R-linear then it is said to be * Irreducible if there is no nonzero proper invariant submodule.
More generally, it is true that every nonzero finitely generated module has a maximal submodule.
The notion of ideal generalises to any Mal'cev algebra (as linear subspace in the case of vector spaces, normal subgroup in the case of groups, two-sided ideals in the case of rings, and submodule in the case of modules ).
