Questions in which polynomials (single or several variables) play a key role. It is typically important that this tag is combined with other tags; polynomials appear in very different contexts. Please, use at least one of the top-level tags, such as nt.number-theory, co.combinatorics, ac.commutative-algebra, in addition to it. Also, note the more specific tags for some special types of polynomials, e.g., orthogonal-polynomials, symmetric-polynomials.

I am seeking reference(s) on the following theorem about sufficient conditions for an entire function with real coefficients to have only real zeros.
Theorem:
Let $f_n(z)=\sum_0^n a_m z^m$ (with $a_m …
