Unified Convergence Analysis of Chebyshev–Halley Methods for Multiple Polynomial Zeros

open access: yesMathematics, 2022
In this paper, we establish two local convergence theorems that provide initial conditions and error estimates to guarantee the Q-convergence of an extended version of Chebyshev–Halley family of iterative methods for multiple polynomial zeros due to ...

Some inequalities for the polar derivative of some classes of polynomials [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2019
In this paper, we investigate an upper bound of the polar derivative of a polynomial of degree where zeros are in and the remaining zeros are outside where .

Location of zeros of Wiener and distance polynomials. [PDF]

open access: yesPLoS ONE, 2012
The geometry of polynomials explores geometrical relationships between the zeros and the coefficients of a polynomial. A classical problem in this theory is to locate the zeros of a given polynomial by determining disks in the complex plane in which all ...

A New Ehrlich-Type Sixth-Order Simultaneous Method for Polynomial Complex Zeros

open access: yesVetor, 2023
This paper presents a new iterative method for the simultaneous determination of simple polynomial zeros. The proposed method is obtained from the combination of the third-order Ehrlich iteration with an iterative correction derived from Li's fourth ...

Upper Bound for Lebesgue Constant of Bivariate Lagrange Interpolation Polynomial on the Second Kind Chebyshev Points

open access: yesJournal of Mathematics, 2022
In the paper, we study the upper bound estimation of the Lebesgue constant of the bivariate Lagrange interpolation polynomial based on the common zeros of product Chebyshev polynomials of the second kind on the square −1,12. And, we prove that the growth

Zero sets of univariate polynomials [PDF]

open access: yesTransactions of the American Mathematical Society, 2010
Let L be the zero set of a nonconstant monic polynomial with complex coefficients. In the context of constructive mathematics without countable choice, it may not be possible to construct an element of L. In this paper we introduce a notion of distance from a point to a subset, more general than the usual one, that allows us to measure distances to ...

Polynomial automata: Zeroness and applications [PDF]

open access: yes2017 32nd Annual ACM/IEEE Symposium on Logic in Computer Science (LICS), 2017
We introduce a generalisation of weighted automata over a field, called polynomial automata, and we analyse the complexity of the Zeroness Problem in this model, that is, whether a given automaton outputs zero on all words. While this problem is non-primitive recursive in general, we highlight a subclass of polynomial automata for which the Zeroness ...

Configuration of Zeros of Isochronous Vector Fields of Degree 5

open access: yesComplexity, 2021
In this paper, we give the algebraic conditions that a configuration of 5 points in the plane must satisfy in order to be the configuration of zeros of a polynomial isochronous vector field.

A condition for associativity of univariate resultants

open access: yesExamples and Counterexamples, 2023
We provide a condition on the occurrences of variables in polynomials and show that it ensures associativity of univariate resultants in non-trivial cases.
