Superelliptic Affine Lie algebras and orthogonal polynomials II

Felipe Albino dos Santos, Mikhail Neklyudov, Vyacheslav Futorny

Let $g$ be a finite-dimensional complex simple Lie algebra and $r, m \geq 2$ . The universal central extension of the superelliptic current algebra $g \otimes A$ i…

Superelliptic Affine Lie algebras and orthogonal polynomials

Felipe Albino dos Santos, Mikhail Neklyudov, Vyacheslav Futorny

We construct two families of orthogonal polynomials associated with the universal central extensions of the superelliptic Lie algebras. These polynomials satisfy certain fourth ord…
