On entire functions from the Laguerre-Polya I class with non-monotonic second quotients of Taylor coefficients

For an entire function $f(z) = \sum_{k=0}^\infty a_k z^k, a_k>0,$ we define its second quotients of Taylor coefficients as $q_k (f):= \frac{a_{k-1}^2}{a_{k-2}a_k}, k \geq 2.$ In the present paper, we

Complex zero decreasing sequences

The purpose of this paper is to investigate the real sequences γ0, γ1, γ2, . . . with the property that if p(x) = ∑n k=0 akx k is any real polynomial, then ∑n k=0 γkakx k has no more nonreal zeros

The bivariate series defines a partial theta function. For fixed q (∣q∣ < 1), θ(q, ·) is an entire function. For q ∈ (–1, 0) the function θ(q, ·) has infinitely many negative and infinitely many

On the Closest to Zero Roots and the Second Quotients of Taylor Coefficients of Entire Functions from the Laguerre–Pólya I Class

For an entire function $$f(z) = \sum _{k=0}^\infty a_k z^k, a_k>0$$ f ( z ) = ∑ k = 0 ∞ a k z k , a k > 0 , we show that if f belongs to the Laguerre–Pólya class, and the quotients $$q_k:=

HARDY-PETROVITCH-HUTCHINSON'S PROBLEM AND PARTIAL THETA FUNCTION

In 1907, M. Petrovitch initiated the study of a class of entire functions all whose finite sections (i.e., truncations) are real-rooted polynomials. He was motivated by previous studies of E.

Partial Theta Functions. I. Beyond the Lost Notebook

It is shown how many of the partial theta function identities in Ramanujan's lost notebook can be generalized to infinite families of such identities. Key in our construction is the Bailey lemma and
