Some inequalities and an application of exponential polynomials

open access: yes, 2020
In the paper, with the help of the Faà di Bruno formula, properties of the Bell polynomials of the second kind, and the inversion theorem for the Stirling numbers of the first and second kinds, the author presents an explicit formula and an identity for ...

Some special finite sums related to the three-term polynomial relations and their applications

open access: yesAdvances in Differential Equations, 2014
We define some finite sums which are associated with the Dedekind type sums and Hardy-Berndt type sums. The aim of this paper is to prove a reciprocity law for one of these sums. Therefore, we define a new function which is related to partial derivatives

A new bound on cofactors of sparse polynomials

open access: yesForum of Mathematics, Sigma
We prove that for polynomials $ f, g, h \in \mathbb {Z}[x] $ satisfying $ f = gh $ and $ f(0) \neq 0 $ , the $\ell _2$ -norm of the cofactor $ h $ is bounded by $$ \begin{align*} \left\Vert {h} \right\Vert{}_2\leq ...

Squarefree values of polynomial discriminants II

open access: yesForum of Mathematics, Pi
We determine the density of integral binary forms of given degree that have squarefree discriminant, proving for the first time that the lower density is positive. Furthermore, we determine the density of integral binary forms that cut out maximal orders

Root multiplicities and number of nonzero coefficients of a polynomial

open access: yes, 2005
It is known that the weight (that is, the number of nonzero coefficients) of a univariate polynomial over a field of characteristic zero is larger than the multiplicity of any of its nonzero roots.

Feasibility of primality in bounded arithmetic

open access: yesForum of Mathematics, Sigma
We prove the correctness of the AKS algorithm [1] within the bounded arithmetic theory $T^{\text {count}}_2$ or, equivalently, the first-order consequences of the theory $\text {VTC}^0$ expanded by the smash function, which we denote by

Improvements on dimension growth results and effective Hilbert’s irreducibility theorem

open access: yesForum of Mathematics, Sigma
We sharpen and generalize the dimension growth bounds for the number of points of bounded height lying on an irreducible algebraic variety of degree d, over any global field.

Integral orthogonal bases of small height for real polynomial spaces [PDF]

open access: yes, 2009
Let $P_N(R)$ be the space of all real polynomials in $N$ variables with the usual inner product $$ on it, given by integrating over the unit sphere. We start by deriving an explicit combinatorial formula for the bilinear form representing this inner ...

Classification and irreducibility of a class of integer polynomials

open access: yesOpen Mathematics
We find all integer polynomials of degree dd that take the values ±1\pm 1 at exactly dd integer arguments, and determine the irreducibility of these polynomials by means of an elementary approach.

Identities Involving Zeros of Ramanujan and Shanks Cubic Polynomials [PDF]

open access: yes, 2014
In this paper we highlight the connection between Ramanujan cubic polynomials (RCPs) and a class of polynomials, the Shanks cubic polynomials (SCPs), which generate cyclic cubic fields.
