On combinatorial properties and the zero distribution of certain Sheffer sequences

Gi-Sang Cheon, Tamás Forgács, Hana Kim +1

We present combinatorial and analytical results concerning a Sheffer sequence with a generating function of the form $G(x,z)=Q(z{)}^{x}Q(-z{)}^{1-x}$, where $Q$ is a quadratic polynomi…
