Abstract: Many intuitively valid arguments involving intensionality cannot be captured by first-order logic, even when extended by modal and epistemic operators.

Indeed, previous attempts at providing an adequate treatment of the phenomenon of intensionality in logic and language, such as those of Frege, Church, Russell, Carnap, Quine, Montague and others are fraught with numerous philosophical and technical difficulties and shortcomings.

O Departamento de Matemática promove duas sessões de boas-vindas aos novos alunos 2020/2021:

• Licenciatura em Matemática: “Clube Ciências” (edifício C6) | 2 sessões presenciais: números pares das 15h00 às 15h30, números ímpares das 15h45 às 16h15
• Licenciatura em Matemática Aplicada: Zoom | 08h30 (sessão organizada com o DEIO)

Abstract: The Kicked Rotator is one of the central models in studies of chaos theory. Its quantization was the subject of great interest in the 1980's, but since the 1990's, interest faded. I hope to rekindle interest in this subject.

Fractals are beautiful mathematical objects and are everywhere. It is possible and widely known how such objects are constructed mathematically. A fascinating challenge is how can a fractal pattern be mathematically found from real data? Let us remember that a fractal is chaotic, a dynamic system very sensitive to initial conditions. In this seminar I will present a method that I developed to find fractal functions that approximate real data.

We study an interaction model of a large population of players based on an evolutionary game, which describes the dynamical process of how the distribution of strategies changes in time according to their individual success.

Este encontro científico visa dar a conhecer o trabalho dos membros do Centro de Matemática, Aplicações Fundamentais e Investigação Operacional (CMAFcIO), bem como o de colegas de áreas afins pertencentes a outras Unidades de Investigação e promover, na medida do possível, a interação entre os seus participantes.
