    What's Weyl group? - ProProfs

    What's Weyl group?

    • It's a subgroup of isometry group of the system.

    • It's a subgroup of metric group of the root system.

    • It's a subgroup of isometry group of the root system.

    • It's a subgroup of geometry group of the root system.

    Correct Answer
    A. It's a subgroup of isometry group of the root system.
    Explanation
    The Weyl group is a subgroup of the isometry group of the root system. The root system is a collection of vectors that encode the geometric properties of a Lie algebra. The Weyl group acts on the root system by permuting and reflecting the roots while preserving the angles between them. It plays a fundamental role in the study of Lie algebras and Lie groups, as it captures the symmetries of the root system and provides important information about the structure and representation theory of these mathematical objects.

    How is an affine Hecke algebra depicted? - ProProfs

    How is an affine Hecke algebra depicted?

    • L (Σ, Q)

    • H (Σ, q)

    • Q(Σ, h)

    • H (L,H)

    Correct Answer
    A. H (Σ, q)
    Explanation
    An affine Hecke algebra is depicted by the notation H (Σ, q). This notation represents the algebraic structure used to study certain types of symmetries in mathematics. The Σ represents a set of generators, which are elements that generate the algebra. The q represents a parameter that is used in defining the algebraic operations within the Hecke algebra. Therefore, H (Σ, q) is the correct depiction of an affine Hecke algebra.

    What's an affine root system? - ProProfs

    What's an affine root system?

    • It's a system of affine-linear function on a Euclidean space.

    • It's a root system of affine-linear function on a space.

    • It's a root system of affine-linear function on a Euclidean space.

    • It's a root system of a linear function on a Euclidean space.

    Correct Answer
    A. It's a root system of affine-linear function on a Euclidean space.
    Explanation
    An affine root system refers to a root system of affine-linear functions on a Euclidean space. This means that the root system consists of vectors that satisfy certain properties under affine-linear transformations, such as translations and reflections, in a Euclidean space. The term "affine-linear" emphasizes the combination of affine transformations and linear functions in defining the root system.

    What's an associative algebra? - ProProfs

    What's an associative algebra?

    • It's an algebraic structure with compatible operation of addition by elements in some field.

    • It's an algebraic structure with compatible operation of multiplication by elements in some field.

    • It's an algebraic structure with compatible operation of addition, multiplication, and a scalar multiplication by elements in some field.

    • It's an algebraic structure with compatible operation of addition, and a scalar multiplication by elements in some field.

    Correct Answer
    A. It's an algebraic structure with compatible operation of addition, multiplication, and a scalar multiplication by elements in some field.
    Explanation
    The correct answer explains that an associative algebra is an algebraic structure that has compatible operations of addition, multiplication, and scalar multiplication by elements in some field. This means that the algebra satisfies the associative property for addition and multiplication, and also allows for scalar multiplication by elements from a field. This definition encompasses all the necessary operations for an associative algebra.

    What's a multiplicity function? - ProProfs

    What's a multiplicity function?

    • It's a number of spin states such as n of the N spins point in the Z direction

    • It's a number of states such as n of the A spins point in the Z direction

    • It's a number of spin states such as n of the N spins point in the M direction

    • It's a number of spin states such as n of the Z spins point in the N direction

    Correct Answer
    A. It's a number of spin states such as n of the N spins point in the Z direction
    Explanation
    The multiplicity function refers to the number of spin states in which n of the N spins point in the Z direction. In other words, it represents the number of possible arrangements or configurations of spins where a specific number of spins align in the Z direction out of the total N spins.
