Lattice-points enumeration in polytopes Study of the coefficients of the Ehrhart quasi-polynomial

open access: yes, 2017
A very important problem in discrete geometry is counting points with integer-coordinates (also called "lattice-points") in polytopes. A polytope is a geometric shape that is the smallest convex set containing the vertices defining the polytope.

Improving georeferencing accuracy of Very High Resolution satellite imagery using freely available ancillary data at global coverage

open access: yesInternational Journal of Digital Earth, 2017
While impressive direct geolocation accuracies better than 5.0 m CE90 (90% of circular error) can be achieved from the last DigitalGlobe’s Very High Resolution (VHR) satellites (i.e.

Upper bounds for the number of factors for a class of polynomials with rational coefficients [PDF]

open access: yesActa Arithmetica, 2004
Let \(f(X),g(X)\in{\mathbb Q}[X]\) be two relatively prime polynomials, with \(\deg(f) < \deg(g)\). Using Hilbert's irreducibility theorem, \textit{M. Cavachi} [J. Number Theory 82, 96--99 (2000; Zbl 0985.12001)] proved that the polynomial \(f(X)+pg(X)\) is irreducible for infinitely many rational primes \(p\). Later on, \textit{M. Cavachi, M. Vâjâitu}

A NEW GENERATOR OF THIRD-DEGREE LINEAR FORMS

open access: yesПроблемы анализа
This paper examines linear forms of the third-degree, i.e., when the associated Stieltjes function satisfies a cubic equation with polynomial coefficients. A generator for third-degree forms is constructed. In fact, we study the stability of the third-

Double-Scale Expansions for a Logarithmic Type Solution to a q-Analog of a Singular Initial Value Problem

open access: yesAbstract and Applied Analysis
We examine a linear q−difference differential equation, which is singular in complex time t at the origin. Its coefficients are polynomial in time and bounded holomorphic on horizontal strips in one complex space variable.

Counting hyperelliptic curves that admit a Koblitz model

open access: yesJournal of Mathematical Cryptology, 2008
Let be a finite field of odd characteristic. We find a closed formula for the number of k-isomorphism classes of pointed, and non-pointed, hyperelliptic curves of genus g over k, admitting a Koblitz model.

Recurrence relations for the coefficients in Chebyshev series solutions of ordinary differential equations

open access: yes, 1980
Systematic methods are presented for obtaining recurrence relations for the coefficients in Chebyshev series solutions of linear differential equations, of first to fourth order, with polynomial coefficients. Polynomial approximations to certain rational
