Limits of zeros of polynomial sequences
, 2007 In the present paper we consider $F_k(x)=x^{k}-\sum_{t=0}^{k-1}x^t,$ the characteristic polynomial of the $k$-th order Fibonacci sequence, the latter denoted $G(k,l).$ We determine the limits of the real roots of certain odd and even degree polynomials related to the derivatives and integrals of $F_k(x),$ that form infinite sequences of polynomials, of

Construction of zero correlation zone Gaussian integer sequence set
Tongxin xuebao, 2017 The construction of zero correlation zone (ZCZ) Gaussian integer sequence set was researched.Based on binary orthogonal matrices,ZCZ ternary sequence sets were constructed by adding zeros at first.Then the ternary ZCZ squences were transformed into ...

ZERO-INTERPOLATING SEQUENCESWe introduce several topics for sequences in the unit disc of the complex plane and the space of bounded analytic functions. We characterize sequences that are the union of one interpolating subsequence and one zero subsequence. We also require the interpolation of the derivative and that it vanishes where the function does.

Maximal zero sequences for Fock spaces
, 2011 A sequence $Z$ in the complex plane $\C$ is called a zero sequence for the Fock space $F^p_ $ if there exists a function $f\in F^p_ $, not identically zero, such that $Z$ is the zero set of $f$, counting multiplicities. We show that there exist zero sequences $Z$ for $F^p_ $ with the following properties: (1) For any $a\in\C$ the sequence $Z\cup\{a\}
