Superelliptic Affine Lie algebras and orthogonal polynomials
Forum of Mathematics, SigmaWe construct two families of orthogonal polynomials associated with the universal central extensions of the superelliptic Lie algebras. These polynomials satisfy certain fourth-order linear differential equations, and one of the families is a particular ...

Chebyshev systems and Sturm oscillation theory for discrete polynomials
Forum of Mathematics, SigmaWe prove an analogue of Chebyshev’s alternation theorem for linearly independent discrete functions $\Phi _n=\{\varphi _k\}_{k=1}^n$ on the interval $[0,q]_{\scriptscriptstyle \mathbb {Z}}=[0,q]\cap \mathbb {Z}$ . In particular, we establish

Integer-valued polynomials satisfying growth constraints
Forum of Mathematics, SigmaWe consider polynomials which take integer values on the integers (IVPs), and satisfy an additional growth condition on the natural numbers. Elkies and Speyer, answering a question by Dimitrov, showed that there is a critical exponential growth threshold,
