## 1. Multiplier sequences and CZDS

1. #### Problem 1.1.

[A. Vishnyakova] Let $\{c_k\}_{k=0}^n\subset\mathbb{R}$ be given. Does there exist a real rooted polynomial, $p(x)$, with zeros outside $[0,n]$ such that $c_k=p(k)$, $k=0,1,\ldots,n$?
Note that this implies $\{c_k\}_{k=0}^n$ is an n-CZDS.
• #### Problem 1.2.

[G. Csordas] Let $f(z)$ be a meromorphic function. When is the sequence $\{f(k)\}_{k=0}^\infty$ a multiplier sequence?
