Abstract: The work presents a historical overview of game theory, highlighting the contributions of prominent mathematicians to the development of this field. Its objective is to introduce different types of games, their solutions through dominant strategies or Nash Equilibrium, as well as to solve classic examples, such as the Prisoner’s Dilemma. Additionally, the results of an educational application conducted at a public school in Alagoas are presented, followed by the conclusions drawn.2025-08-22T00:00:00ZJogos de diagonalização: uma abordagem para o estudo de sequênciasCarvalho, Cinthia Rodrigues dehttps://ri.ufs.br/jspui/handle/riufs/239192025-11-25T17:57:34Z2025-08-08T00:00:00ZTítulo: Jogos de diagonalização: uma abordagem para o estudo de sequências

Abstract: The aim of this work is to present a combinatorial game inspired by Cantor’s diagonalization argument. The game involves two players, Kronecker and Cantor, whose names
reference the historical opposition of Leopold Kronecker to the mathematics developed
by Georg Cantor. Based on the arguments explored in the game, we propose a didactic
approach aimed at teaching concepts related to sequences and the cardinality of sets,
introducing the idea of infinite sets and their distinctions.2025-08-08T00:00:00ZA álgebra linear das matrizes no estudo da dinâmica de um braço robótico articuladoSampaio, Hélio Luiz Oliveirahttps://ri.ufs.br/jspui/handle/riufs/236392025-10-30T17:53:10Z2025-08-29T00:00:00ZTítulo: A álgebra linear das matrizes no estudo da dinâmica de um braço robótico articulado

Abstract: This text aims to propose an interdisciplinary approach to the study of matrices,
with an emphasis on the mathematical formulation of an articulated robotic arm model.
Using basic concepts from linear algebra — especially the study of matrices associated
with linear transformations, homogeneous coordinates, eigenvalues, and eigenvectors —
we present the main matrix properties applied to the model of a simple robotic arm with
a single degree of freedom, consisting of a base and a straight arm, subjected to rigid
translation and rotation movements around an axis. Finally, we propose a pedagogical
intervention in high school, motivated by the need to facilitate the understanding of the
presented robotic model. With the aid of the GeoGebra software, students were able to
establish connections between theoretical knowledge and practical applications related to
matrix content, promoting more meaningful and integrated learning.2025-08-29T00:00:00ZO uso do conceito de séries para demonstrar a igualdade “0,999...=1”Dantas Junior, Carlos Roberto Santoshttps://ri.ufs.br/jspui/handle/riufs/232302025-09-24T13:09:07Z2025-08-21T00:00:00ZTítulo: O uso do conceito de séries para demonstrar a igualdade “0,999...=1”

Abstract: This work aims to rigorously present a justification for the equality 0.999 . . . = 1, which often causes confusion among students and mathematics enthusiasts. It is worth noting that this equality is related to the very history of the construction of the real numbers and the concept of infinity in mathematics. It was through the work of Augustin-Louis Cauchy (1789−1857) and Karl Weierstrass (1815−1897) that the foundations of calculus and real analysis were consolidated, allowing the equality 0.999 . . . = 1 to be treated precisely. In the 20th century, with the formalization of the real numbers through Cauchy sequences or Dedekind cuts, it became clear that this equality refers to a sequence that converges (or “approaches”) 1.2025-08-21T00:00:00Z
