This article exposes a work for continuing education of art and mathematics teachers of basic education, focusing on the teaching of geometry through tessellations. We emphasize the constitution of a nucleus of ideas formed ... -
Fixed points on trivial surface bundles over a connected CW-complex
; Libardi, Alice Kimie Miwa; ; Vieira, João Peres (Publicationes Mathematicae, 2015) [Artigo]
The main purpose of this work is to study fixed points of fibre-preserving maps over a connected CW-complex B on the trivial surface bundles B×S where S is a closed surface of negative Euler characteristic. The case where ... -
Remarks on the existence and uniqueness of periodic solution for nth-order functional differential equations with infinite delay
Afonso, S. M.; (Dynamics of Continuous, Discrete and Impulsive Systems Series A: Mathematical Analysis, 2018) [Artigo]
In this work we apply the coincidence degree theory to establish a result on the existence and uniqueness of periodic solution for a class of nth-order functional differential equations with infinite delay. An example is ... -

Movimentos de Teorizações em Educação Matemática
Viola Dos Santos, João Ricardo; Lins, Romulo Campos (Bolema - Mathematics Education Bulletin, 2016) [Artigo]
In this essay, we show a discussion about a process of theorization in Mathematics Education. In the first part, by means of an interview textualization, we elaborated a theorization movement about mathematical preparation ... -
Lefschetz coincidence class for several maps
Monis, Thaís F. M.; (Journal of Fixed Point Theory and Applications, 2016) [Artigo]
The aim of this paper is to define a Lefschetz coincidence class for several maps. More specifically, for maps (Formula presented.) from a topological space X into a connected closed n-manifold (even nonorientable) N, a ... -
Coincidence of maps on torus fibre bundles over the circle
Vieira, João Peres (Topological Methods in Nonlinear Analysis, 2015) [Artigo]
The main purpose of this work is to study coincidences of fibre- preserving self-maps over the circle S1 for spaces which are fibre bundles over S1 and the fibre is the torus T. We classify all pairs of self-maps over S1 ... -
Functions and vector fields on C(ℂPn)-singular manifolds
Libardi, Alice Kimie Miwa; (Topological Methods in Nonlinear Analysis, 2015) [Artigo]
In this paper we study functions and vector fields with isolated singularities on a C(ℂPn)-singular manifold. In general, a C(ℂPn)-singular manifold is obtained from a smooth (2n + 1)-manifold with boundary which is a ... -
