Counting integers representable as images of polynomials modulo n
(Cartagena de Indias, 2019)
Given a polynomial f(x1,x2,…,xt) in t variables with integer coefficients and a positive integer n, let α(n) be the number of integers 0 ≤ a < n such that the polynomialcongruencef(x1,x2,…,xt) ≡ a(modn)issolvable. ...
Polinômios ortogonais e L-ortogonais associados a medidas relacionadas
(Universidade Estadual Paulista (Unesp), 2011-01-20)
O objetivo deste trabalho é fazer um estudo das propriedades de duas sequências de polinômios, {Pϕ0 n }∞ n=0 e {Pϕ1 n }∞ n=0, ortogonais com relação, respectivamente, às medidas dϕ0 e dϕ1, relacionadas entre si, e das ...

Companion orthogonal polynomials: some applications
(Elsevier B.V., 2001-11-01)
In this paper the recurrence relations of symmetric orthogonal polynomials whose measures are related to each other in a certain way are considered. Many of the relations satisfied by the coefficients of the recurrence ...

Legendre polynomials based feature extraction for online signature verification. Consistency analysis of feature combinations
(Elsevier, 2014-01)
In this paper, feature combinations associated with the most commonly used time functions related to the signing process are analyzed, in order to provide some insight on their actual discriminative power for online signature ...
Sign conditions for the existence of at least one positive solution of a sparse polynomial system
(Academic Press Inc Elsevier Science, 2020-12)
We give sign conditions on the support and coefficients of a sparse system of d generalized polynomials in d variables that guarantee the existence of at least one positive real root, based on degree theory and Gale duality. ...
Christoffel formula for kernel polynomials on the unit circle
(2018-11-01)
Given a nontrivial positive measure μ on the unit circle T, the associated Christoffel–Darboux kernels are Kn(z,w;μ)=∑k=0 nφk(w;μ)¯φk(z;μ), n≥0, where φk(⋅;μ) are the orthonormal polynomials with respect to the measure μ. ...
