Zeros of Bernoulli, generalized Bernoulli and Euler polynomials. (English) Zbl 0645.10015
Author’s abstract: “It is shown that the Bernoulli polynomials $B\sb n(z)$, the Euler polynomials $E\sb n(z)$ and the generalized Bernoulli polynomials $B\sp n\sb{\chi}(z)$ associated with certain quadratic characters have no zero inside a parabolic region if n is sufficiently large. Zero-free regions are also found for individual polynomials, and for the partial sums of sine and cosine. The proofs are based on a result on the maximum modulus of the zeros of polynomials related to the $B\sb n(z)$, $E\sb n(z)$ and $B\sp n\sb{\chi}(z)$. Finally, the distribution of the real zeros of $B\sp n\sb{\ell}(z)$ and $E\sb n(z)$ is studied. The results are similar to the known results on the real zeros of $B\sb n(z)$.”
