After reviewing some properties of the two dimensional hyperbolic toral automorphism called Arnold's discrete cat map, including its generalizations with matrices having positive unit determinant, this thesis contains a definition of a novel cat map where the elements of the matrix are found in the sequence of Pell numbers. This mapping is therefore denoted as Pell's cat map. The main result of this thesis is a theorem determining the upper bound for the minimal period of Pell's cat map. From numerical results four conjectures regarding properties of Pell's cat map are also stated. A brief exposition of some applications of Arnold's discrete cat map is found in the last part of the thesis.

O objetivo é mostrar como este tema pode vir a ser abordado entre os alunos do Ensino Fundamental e Medio de forma prática e interativa. / In this dissertation, we present a line of research involving incommensurable with a case study of the number of gold, its defnition, its applications, its relationship with the pentagram and the Fibonacci sequence and its curiosities that relate to art and nature. The goal is to show how this theme might be broached among students of middle school and high school in a practical and interactive way.

CAPES / O presente trabalho tem dois objetivos: o primeiro está relacionado ao ensino da análise combinatória nas séries do ensino fundamental 2 e ensino médio. O segundo objetivo e buscar aprofundar meus conhecimentos relacionados aos conceitos combinatoriais. Com relação ao primeiro objetivo, o ensino da análise combinatória, na minha trajetória como docente, tem sido uma das tarefas mais árduas que o professor de matemática da educação básica enfrenta. Diante disso, surgem algumas perguntas. Por que um assunto totalmente aplicável ao cotidiano tem gerado tanta dificuldade de compreensão? Um dos objetivos desse trabalho e buscar respostas para essa pergunta e propor sugestões que possam melhorar o entendimento desse conceito. Como segundo objetivo proposto, busquei compreender conceitos que até então, por mim, não dominados, aprofundando meu conhecimento combinatorial. Para tanto, esse trabalho possui uma parte dedicada ao estudo de conceitos combinatorias mais complexos, não o abordados junto aos alunos de ensino médio mas que permitem compreender situações combinatoriais mais complexas. / The present work has two major goals. The first one is related to the teaching of combinatorics in elementary school and high school. The second one is to seek further knowledge related to combinatorial concepts. Regarding the first goal, the teaching of combinatorics, in my trajectory as a teacher, has been one of the most arduous tasks that the math teacher of basic education faces. Therefore, some questions arise. Why a subject fully applicable to everyday, has generated so much trouble understanding? One of the goals of this work is to seek answers to this question and propose suggestions that can improve the understanding of this concept. As a second proposed goal, I sought to understand concepts that hitherto were not dominated, deepening my combinatorial knowledge. Therefore, this work has section devoted to the study of more complex combinatory concepts, not addressed to the students of high school but they allow us to understand more complex combinatorial situations.

Nesse trabalho, iniciaremos a construção de uma aula, visando orientar o professor sobre como atender as necessidades pedagógicas de um disléxico, seguindo orientações de especialistas sobre o tema. Utilizaremos como ponto de partida, um desafio intrigante para despertar o interesse do aluno e para desenvolver uma estratégia que atenda essas orientações, cuja base é o ensino multissensorial. Abordaremos um dos conceitos mais interessantes do curriculum matemático: a sequência de FIBONACCI / Abstract: This research aims to explore the learning of certain topics of mathematics by dyslexic students and the contribution that art and technology can provide, serving as facilitators instruments in the teaching-learning process. In this work, we will begin the construction of a class in order to guide the teacher on how to meet the educational needs of a dyslexic, following expert recommendations about Dyslexia. We will use as a starting point, an intriguing challenge to pique the interest of the student and to develop a strategy that meets these guidelines, which are based on the multisensory teaching. We will discuss about one of the most interesting concepts of mathematical curriculum: the Fibonacci sequence / Mestrado / Matemática em Rede Nacional / Mestre

This study explores text and music relations in Canadian composer Violet Archer’s “The Twenty-Third Psalm” by analysing the text of Psalm 23, Fibonacci numbers, melodic contours, motives, and the role of the accompaniment. The text focuses on David’s faith in God and his acceptance of God as his shepherd on earth. The four other approaches allow us to examine the work on three different structural levels: background through Fibonacci numbers, middleground through melodic contour analysis, and foreground through motivic analysis and the role of the accompaniment. The measure numbers that align with Fibonacci numbers overlap with some of the melodic contour phrases, which are demarcated by rests, as well as with the most important moments at the surface level, such as the emphasis on the word “death” through recurring and symbolic motives. The piano accompaniment further supports these moments in the text.

This work contains an overview of the results concerning number-theoretic pro- perties of some significant combinatorial sequences such as factorials, binomial coef- ficients, Fibonacci and Catalan numbers. These properties include parity, primality, prime power divisibility, coprimality etc. A substantial part of the text should be accessible to gifted high school students, the results are illustrated with examples. 1

Sequences often occur in many branches of applied mathematics. Recurrence relation is a powerful tool to characterize and study sequences. Some commonly used methods for solving recurrence relations will be investigated. Many examples with applications in algorithm, combination, algebra, analysis, probability, etc, will be discussed. Finally, some well-known contest problems related to recurrence relations will be addressed.
