Development of skills through a math escape room

Today’s students, in addition to acquiring knowledge, must be able to develop other skills, such as critical and creative thinking, problem-solving ability, cooperation, communication in different contexts, autonomy, self-regulation and empathy. In this context, a physical escape room with an original design was created with the objective, not only of developing the aforementioned skills, but also of consolidat...

Algebraic curves associated with centrosymmetric matrices of orders up to 6

On the numerical range of Kac-Sylvester matrices

On the numerical range of Kac-Sylvester matrices

In this paper, the boundary generating curves and the numerical range of Kac-Sylvester matrices up to the order 9 are characterized. Based on the obtained results and on several computational experiments performed with the Mathematica and MatLab programs, we conjecture that the found types of algebraic curves, namely ellipses and ovals, will appear for an arbitrary order.

The 9th International Conference on Matrix Analysis and Applications (ICMAA 2022) was held at the Department of Mathematics of the University of Aveiro in Aveiro, Portugal, June 15–17, 2022. The purpose of this meeting was to stimulate research and interaction among mathematicians working in all aspects of linear and multilinear algebra, matrix analysis, graph theory, and related applications, providing an oppo...

Portuguese older persons' views about living in a nursing home: challenges to t...

This paper addresses the broad topic of what older people think about nursing homes in Portugal. In the aftermath of the COVID-19 pandemic and considering the tragic events taking place in nursing homes, the challenge of reimagining the sector involves not only improving procedures and models of care, making sure they meet what citizens consider adequate, but also rehabilitating the image people have about nurs...
