Deterministically Computing Reduction Numbers of Polynomial Ideals

We discuss the problem of determining reduction number of a polynomial ideal I in n variables. We present two algorithms based on parametric computations. The first one determines the absolute reduction number of I and requires computation in a polynomial ring with (n-dim(I))dim(I) parameters and n-dim(I) variables. The second one computes via a Grobner system the set of all reduction numbers of the ideal I and thus in particular also its big reduction number. However,it requires computations in a ring with n.dim(I) parameters and n variables.Comment: This new version replaces the earlier version arXiv:1404.1721 and it has been accepted for publication in the proceedings of CASC 2014, Warsaw, Polna

On Computing Groebner Basis in the Rings of Differential Operators

Insa and Pauer presented a basic theory of Groebner basis for differential operators with coefficients in a commutative ring in 1998, and a criterion was proposed to determine if a set of differential operators is a Groebner basis. In this paper, we will give a new criterion such that Insa and Pauer's criterion could be concluded as a special case and one could compute the Groebner basis more efficiently by this new criterion

Towards Toric Absolute Factorization

This article gives an algorithm to recover the absolute factorization of a bivariate polynomial, taking into account the geometry of its monomials. It is based on algebraic criterions inherited from algebraic interpolation and toric geometry

The study was conducted in a qualitative perspective using to achieve the proposed objectives the following methodology: literature review, documentary research and empirical research. We analyzed the landmarks and public policies related to adolescence and youth in Brazil, the evolution of the social circus proposed as an alternative teaching from the perspective of nonformal education, in work with children, adolescents and young subaltern classes. For this feasibility study were interviewed using semi-structured, which we accomplished graduates ECDF enrollments between 1998 and 2009 and remained enrolled and attending at least two years. The research revealed that the ECDF, constitutes a major influence on its graduates, towards social emancipation, but work the importance of working with children and youth using the circus, which is characterized by a simple language but very attractive also motivates them to continue participating.Esta dissertação objetiva compreender de que forma a experiência vivenciada na Escola de Circo Dom Fernando ECDF influenciou na formação de crianças e adolescentes da Região Leste de Goiânia identificando o papel desse Programa para os egressos do período de 1998 a 2009. O estudo foi desenvolvido em uma perspectiva qualitativa utilizando para o alcance dos objetivos propostos os seguintes procedimentos metodológicos: revisão bibliográfica, a pesquisa documental e a pesquisa empírica. Foram analisados os marcos históricos e as políticas públicas relacionadas à adolescência e a juventude no Brasil, a evolução da proposta do Circo Social como uma alternativa pedagógica na perspectiva da educação não formal, no trabalho junto a crianças, adolescentes e jovens das classes subalternas. Para viabilização desta pesquisa foram entrevistados por meio de roteiro semiestruturado, egressos da ECDF que efetivaram matrículas entre os anos de 1998 e 2009 e permaneceram matriculados e frequentando por pelo menos um ano. A pesquisa revelou que a ECDF, se constitui em uma grande influência para seus egressos, no sentido de sua emancipação social, além de trabalhar a importância de se trabalhar com o público infanto-juvenil utilizando a arte circense, que tem como característica um linguagem simples, porém muito atrativa que também os motiva a continuar participando
