As diferentes “personalidades” do número racional trabalhadas através da resolução de problemas
(Universidade Estadual Paulista (Unesp), Departamento de Matemática, 2008-01-01)
We address the different "personalities" of the rational number and the concept of proportionality, analyzing the possibilities for using the Mathematics Teaching and Learning through Problem-solving Method. This method ...

On the denominator values and barycentric weights of rational interpolants
(Elsevier B.V., 2007-03-15)
We improve upon the method of Zhu and Zhu [A method for directly finding the denominator values of rational interpolants, J. Comput. Appl. Math. 148 (2002) 341-348] for finding the denominator values of rational interpolants, ...
Estimates on the number of Fq–rational solutions of variants of diagonal equations over finite fields
(Elsevier, 2020-12)
In this paper we study the set of Fq-rational solutions of equations defined by polynomials evaluated in power-sum polynomials with coefficients in Fq. This is done by means of applying a methodology which relies on the ...

Rational places in extensions and sequences of function fields of Kummer type
(Elsevier Science, 2011-11)
In this paper we prove results on the number of rational places in extensions of Kummer type over finite fields and give sufficient conditions for non-trivial lower bounds on the number of rational places at each step ...
The demand for child care subsidies under rationing.
The resources of the Child Care and Development Fund (CCDF) are insufficient to meet the increasing demand for child care subsidies caused by the 1996 welfare reform in the U.S. Since these subsidies are not an entitlement, ...
