About This Quiz

Lie Algebra is possibly another branch of algebra, which is difficult to define or explain. But those who know about it define it as an infinite-dimensional Lie algebra constructed in a canonical fashion out of a finite-dimensional simple Lie algebra. So, how much do you know about this discipline? Take our quiz and find out.

    What's the other term for quantum anomaly? - ProProfs

    What's the other term for quantum anomaly?

    • Quantums

    • Decimals

    • Whole numbers

    • Anomaly

    Correct Answer
    A. Anomaly
    Explanation
    The term "quantum anomaly" refers to an abnormality or deviation from the expected behavior in the field of quantum mechanics. It is a specific type of anomaly that occurs at the quantum level. Therefore, the correct answer is "Anomaly."

    What's an automorphism? - ProProfs

    What's an automorphism?

    • It's an isomorphism from a mathematical object to itself.

    • It's an isomorphic from a mathematical object to itself.

    • It's an metamorphism from a mathematical object to itself.

    • It's an sophism from a mathematical object to itself.

    Correct Answer
    A. It's an isomorphism from a mathematical object to itself.
    Explanation
    An automorphism is a type of isomorphism where a mathematical object is mapped onto itself. Isomorphisms preserve the structure and properties of the objects they map, so an automorphism is a special case where the object is mapped onto itself. This means that the object remains unchanged under the automorphism, maintaining its original properties and relationships.

    What's a semidirect product? - ProProfs

    What's a semidirect product?

    • It's a generalization of a direct product.

    • It's a generalization of a indirect product.

    • It's a generalization of a direct function.

    • It's a generalization of a curve.

    Correct Answer
    A. It's a generalization of a direct product.
    Explanation
    A semidirect product is a generalization of a direct product. In a direct product, two groups are combined by taking the Cartesian product of their elements. In a semidirect product, the groups are still combined, but with an additional operation that allows for non-commutativity between the two groups. This additional operation is defined by a homomorphism from one group to the automorphism group of the other group. This generalization allows for more flexibility and structure in the combined group.

    How many meaning does the Cartan matrix have? - ProProfs

    How many meaning does the Cartan matrix have?

    • 3

    • 2

    • 5

    • 6

    Correct Answer
    A. 3
    Explanation
    The Cartan matrix has three different meanings or interpretations. It can represent the structure of a semisimple Lie algebra, the intersection form on the root lattice, and the Gram matrix of the inner product on the weight lattice. Each of these interpretations provides valuable information about the algebraic structure being studied.

    What's the string theory? - ProProfs

    What's the string theory?

    • It's the theoretical framework in which the point-like particles of particle are replaced by two-dimensional objects called strings.

    • It's the theoretical framework in which the point-like particles of particle are replaced by three-dimensional objects called strings.

    • It's the theoretical framework in which the point-like particles of particle are replaced by five-dimensional objects called strings.

    • It's the theoretical framework in which the point-like particles of particle are replaced by one-dimensional objects called strings.

    Correct Answer
    A. It's the theoretical framework in which the point-like particles of particle are replaced by one-dimensional objects called strings.
    Explanation
    The string theory is a theoretical framework that replaces point-like particles with one-dimensional objects called strings. This theory suggests that these strings vibrate at different frequencies, giving rise to different particles and forces in the universe.

    What's a Dynkin diagram? - ProProfs

    What's a Dynkin diagram?

    • It's a type of graph with some edges.

    • It's a type of graph with some edges doubled or tripled.

    • It's a type of graph with some doubled edges.

    • It's a type of graph with some tripled edges.

    Correct Answer
    A. It's a type of graph with some edges doubled or tripled.
    Explanation
    A Dynkin diagram is a type of graph that represents the root system of a Lie algebra. The edges in the diagram correspond to the roots, which are the fundamental elements of the algebra. In a Dynkin diagram, some edges can be doubled or tripled to indicate certain properties of the root system. This doubling or tripling of edges represents specific relationships between the roots and provides important information about the structure of the Lie algebra.

    What's a group extension in mathematics? - ProProfs

    What's a group extension in mathematics?

    • It's a general means of describing a group in terms of a particular normal group and quotient group.

    • It's a general means of describing a group in terms of a particular normal group and quotient subgroup.

    • It's a general means of describing a group in terms of a particular normal subgroup and quotient group.

    • It's a general means of describing a normal subgroup and quotient group.

    Correct Answer
    A. It's a general means of describing a group in terms of a particular normal subgroup and quotient group.
    Explanation
    A group extension in mathematics is a general means of describing a group by specifying a particular normal subgroup and quotient group. This allows for a more detailed understanding of the group structure and the relationships between its subgroups. By identifying the normal subgroup and quotient group, we can gain insight into the group's properties and study its behavior in a more systematic way.

    What's a lining form? - ProProfs

    What's a lining form?

    • It's a symmetric linear form that plays a basic role in the theories of Lie groups and Lie algebras.

    • It's a symmetric tri linear form that plays a basic role in the theories of Lie groups and Lie algebras.

    • It's a symmetric bi linear form that plays a basic role in the theories of Lie groups and and shapes.

    • It's a symmetric bi linear form that plays a basic role in the theories of Lie groups and Lie algebras.

    Correct Answer
    A. It's a symmetric bi linear form that plays a basic role in the theories of Lie groups and Lie algebras.
    Explanation
    A lining form is a symmetric bi-linear form that is important in the study of Lie groups and Lie algebras. This type of form is used to define the structure and properties of these mathematical objects. It is symmetric, meaning that it is invariant under the exchange of its two arguments, and bi-linear, meaning that it is linear in each argument separately. This form is fundamental in understanding the relationships and interactions within Lie groups and Lie algebras.
