About This Quiz

Despite the fact that not all simple modules have a simple submodule, every simple module is generated by one element. Meanwhile, the idea of simple modules is particularly connected in the ring theory field of mathematics. In group theory, simple modules are analogous to simple groups. They also create building blocks for the modules of finite length.

    What is a collection of finitary operations on a carrier set? - ProProfs

    What is a collection of finitary operations on a carrier set?

    • Modular structure

    • Algebraic structure

    • Structural abstract

    • Simple module

    Correct Answer
    A. Algebraic structure
    Explanation
    An algebraic structure refers to a collection of finitary operations on a carrier set. This means that the operations defined within the structure can be performed on elements of the set, allowing for the study of various mathematical properties and relationships. The term "algebraic" implies that the structure follows algebraic rules and properties, such as closure, associativity, and distributivity. Therefore, the correct answer is algebraic structure.

    Which is not an abstract algebra? - ProProfs

    Which is not an abstract algebra?

    • Slopes

    • Modules

    • Vector spaces

    • Lattice

    Correct Answer
    A. Slopes
    Explanation
    Slopes is not an abstract algebra because it does not fit into the typical framework of abstract algebra, which deals with the study of algebraic structures and their properties. Slopes, on the other hand, are a concept in geometry that describe the steepness or incline of a line. While abstract algebra includes topics such as modules, vector spaces, and lattices, slopes do not fall under this category.

    What is a unified way of expressing properties and constructions that are similar for various structures? - ProProfs

    What is a unified way of expressing properties and constructions that are similar for various structures?

    • Ring theory

    • Group theory

    • Category theory

    • Abstract theory

    Correct Answer
    A. Category theory
    Explanation
    Category theory provides a unified way of expressing properties and constructions that are similar for various structures. It allows for the study of different mathematical objects and their relationships, focusing on the common structures and patterns that exist across different categories. By providing a framework for abstraction and generalization, category theory enables mathematicians to understand and analyze diverse mathematical structures in a unified manner.

    How many elements has a cyclic module? - ProProfs

    How many elements has a cyclic module?

    • 1

    • 2

    • 3

    • 4

    • 5

    Correct Answer
    A. 1
    Explanation
    A cyclic module has only one element. This is because a cyclic module is generated by a single element, called a generator, and all other elements in the module can be obtained by repeatedly applying the module's addition operation to the generator. Therefore, a cyclic module consists of the generator element and no other elements.

    Which is a completely reducible module also called? - ProProfs

    Which is a completely reducible module also called?

    • Semi simple

    • Simple

    • Torsional

    • Zero

    Correct Answer
    A. Semi simple
    Explanation
    A completely reducible module is also called a semi simple module. This means that the module can be decomposed into a direct sum of simple submodules, where a simple module is one that has no nontrivial proper submodules. Therefore, the correct answer is "Semi simple".

    Which is a non-zero module that cannot be written as a direct sum of two non-zero submodules? - ProProfs

    Which is a non-zero module that cannot be written as a direct sum of two non-zero submodules?

    • Indecomposable

    • Noetherain

    • Torsion

    • Simple

    Correct Answer
    A. Indecomposable
    Explanation
    An indecomposable module is a non-zero module that cannot be written as a direct sum of two non-zero submodules. This means that it cannot be decomposed or broken down into smaller submodules. Therefore, the correct answer is indecomposable.

    Which module satisfies the ascending chain condition on submodules? - ProProfs

    Which module satisfies the ascending chain condition on submodules?

    • Noetherain

    • Indecompossable

    • Decomposable

    • Torsion

    Correct Answer
    A. Noetherain
    Explanation
    Noetherian modules satisfy the ascending chain condition on submodules. This means that for any sequence of submodules in a Noetherian module, there exists a point where the sequence stabilizes and no further submodules can be added. This property is named after Emmy Noether, who made significant contributions to the field of abstract algebra.

    Which kind of modules is direct summands of free modules? - ProProfs

    Which kind of modules is direct summands of free modules?

    • Projective

    • Simple

    • Cyclic

    • Noetherain

    Correct Answer
    A. Projective
    Explanation
    Projective modules are direct summands of free modules. This means that if a module is projective, it can be embedded as a direct summand in a free module. In other words, every projective module is a direct summand of a free module. Therefore, the correct answer is projective.

    Which module embeds into its algebraic dual? - ProProfs

    Which module embeds into its algebraic dual?

    • Noetherain

    • Torsionless

    • Torsion-free

    • Reducible

    Correct Answer
    A. Torsionless
    Explanation
    The module that embeds into its algebraic dual is called torsionless. This means that for every element in the module, its annihilator is trivial, i.e., it does not have any non-zero element that annihilates it. This property allows the module to be embedded into its dual, which consists of all linear functionals on the module. Therefore, the correct answer is torsionless.
