Target class: family of symmetric polynomials
Context triple: [Jack polynomials, instanceOf, family of symmetric polynomials]

• A. two-parameter symmetric functions
  Two-parameter symmetric functions are symmetric functions in countably many variables that depend on two additional parameters, typically used to interpolate or generalize classical symmetric function bases such as Schur, Hall–Littlewood, or Macdonald polynomials.
• B. theory of polynomial sequences
  A theory of polynomial sequences studies families of polynomials indexed by integers (or other discrete parameters), analyzing their algebraic, combinatorial, and analytic properties and the relations between successive terms.
• C. list of q-series identities
  A list of q-series identities is a collection of mathematical equalities involving q-series—power series in a variable q—often expressing relationships between infinite sums, products, and special functions in areas such as combinatorics, number theory, and modular forms.
• D. Laurent polynomial-valued invariant
  A Laurent polynomial-valued invariant is a quantity assigned to mathematical objects (such as knots, links, or manifolds) that remains unchanged under specified transformations and takes the form of a Laurent polynomial in one or more variables.
• E. result in q-series theory
  A result in q-series theory is a proven mathematical statement describing properties, identities, or relationships involving power series whose coefficients and exponents depend on a parameter q, often connecting combinatorics, number theory, and special functions.
• F. None of above. chosen
