THE TEACHING OF ARITHMETIC IN THE TEACHER TRAINING COURSE AND THE CONSTITUTION OF AN EXPERT IN THE SYSTEMATIZATION OF THIS KNOWLEDGE IN TIMES OF THE NEW SCHOOL (1950-1970)
(2019)
This text seeks to highlight the processes of production, systematisation and objectivation of mathematical knowledge practised by the teacher Rizza de Araújo Porto in her trajectory, seeking to identify the constitution ...
Improved bounds on the dimensions of sets that avoid approximate arithmetic progressions
(Birkhauser Boston Inc, 2021-02)
We provide quantitative estimates for the supremum of the Hausdorff dimension of sets in the real line which avoid ε-approximations of arithmetic progressions. Some of these estimates are in terms of Szemerédi bounds. In ...

The present study addresses the systematization of the professional knowledge of the teacher who will teach arithmetic in the primary course in the 1950s, in Brazil. This study is part of the Thematic Project entitled ...
Problemas de aritmética em tempos da aritmética intuitiva: uma análise em livros didáticos (1890-1930)
(Universidade Federal de São Paulo (UNIFESP), 2020-12-17)
This master's thesis is based on the perspective of cultural history. Discusses the use of arithmetic problems in times of the intuitive method. Thus, when looking for works that contributed to the understanding of that ...

The inverse Sieve problem in high dimensions
(Duke University Press, 2012-07)
We show that if a big set of integer points S ⊆ [0, N] d, d > 1, occupies few residue classes mod p for many primes p, then it must essentially lie in the solution set of some polynomial equation of low degree. This answers ...
