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.

Speaker: Marco Morandotti (Politecnico di Torino).

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.

Speaker: Elvira Zappale (Università Degli Studi di Salerno).

I will present several integral representation results for certain functionals arising in the context of optimal design and damage models, in presence of a perimeter penalization term. I will consider several frameworks, and I will also discuss the case with non-standard growth conditions.

Abstract: We present some novel kinds of rates of metastability extracted from proofs in classical analysis and ergodic theory that we recently analyzed using proof mining techniques..

Abstract: The Weil conjectures (proved by Deligne in the 70's) played a key role in the development of modern algebraic geometry. In this talk, making use of some recent topological "technology", I will extended the Weil conjectures from the realm of algebraic geometry to the broad noncommutative setting of differential graded categories. Moreover, I will prove the noncommutative Weil conjectures in some interesting cases.
