The zero locus and some combinatorial properties of certain exponential Sheffer sequences

Gi-Sang Cheon, Tamás Forgács, Arnauld Mesinga Mwafise +1

We present combinatorial and analytical results concerning a Sheffer sequence with an exponential generating function of the form $G (s, z) = e^{cz s + α z^{2} + β z^{4}}$ , where $α, β, c \in…

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…
