Find elementary symmetric polynomials
WebWe studied the Gaudin models with gl(1 1) symmetry that are twisted by a diagonal matrix and defined on tensor products of polynomial evaluation gl(1 1)[t]-modules. Namely, we gave an explicit description of the algebra of Hamiltonians (Gaudin Hamiltonians) acting on tensor products of polynomial evaluation gl(1 1)[t]-modules and showed that a bijection … WebIn mathematics, specifically in commutative algebra, the power sum symmetric polynomials are a type of basic building block for symmetric polynomials, in the sense that every symmetric polynomial with rational coefficients can be expressed as a sum and difference of products of power sum symmetric polynomials with rational coefficients. …
