An approximate solution of one singular integro-differential equation using the method of orthogonal polynomials

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2020
Two computational schemes for solving boundary value problems for a singular integro-differential equation, which describes the scattering of H-polarized electromagnetic waves by a screen with a curved boundary, are constructed.

Inequalities for the Polar Derivative of a Polynomial

open access: yesJournal of Inequalities and Applications, 2009
In this paper we obtain new results concerning maximum modulus of the polar derivative of a polynomial with restricted zeros. Our results generalize and refine upon the results of Aziz and Shah [An integral mean estimate for polynomial, Indian J. Pure Appl. Math.

On the irrationality of moduli spaces of projective hyperk\"ahler manifolds [PDF]

open access: yesÉpijournal de Géométrie Algébrique
The aim of this paper is to estimate the irrationality of moduli spaces of hyperk\"ahler manifolds of types K3$^{[n]}$, Kum$_{n}$, OG6, and OG10. We prove that the degrees of irrationality of these moduli spaces are bounded from above by a universal

Effect of Structural Uncertainty in Passive Microwave Soil Moisture Retrieval Algorithm

open access: yesSensors, 2020
Passive microwave sensors use a radiative transfer model (RTM) to retrieve soil moisture (SM) using brightness temperatures (TB) at low microwave frequencies. Vegetation optical depth (VOD) is a key input to the RTM. Retrieval algorithms can analytically

Inequalities for the polar derivative of a polynomial [PDF]

open access: yesThe Journal of Analysis, 2020
Let P(z) be a polynomial of degree n having all its zeros in $$|z|\le 1$$ , then according to Turan (Compositio Mathematica 7:89–95, 2004) $$\begin{aligned} \max \limits _{|Z|=1}|P'(z)|\ge ...

Isomorphism of Compactifications of Vector Bundles Moduli: Nonreduced Moduli

open access: yesМоделирование и анализ информационных систем, 2015
We continue the study of the compactification of the moduli scheme for Gieseker-semistable vector bundles on a nonsingular irreducible projective algebraic surface S with polarization L, by locally free sheaves.

Modular polynomials for genus 2 [PDF]

open access: yes, 2008
Modular polynomials are an important tool in many algorithms involving elliptic curves. In this article we investigate their generalization to the genus 2 case following pioneering work by Gaudry and Dupont.

On polar relations of abstract homogeneous polynomials [PDF]

open access: yesTransactions of the American Mathematical Society, 1976
In this paper we generalize, to vector spaces over algebraically closed fields of characteristic zero, two well-known classical results due to Laguerre and Grace, concerning, respectively, the relative location of the zeros of a complex-valued polynomial and its polar-derivative and the relative location of the zeros of two apolar polynomials.
