Double rotations are the simplest subclass of interval translation mappings. A double rotation is of finite type if its attractor is an interval and of infinite type if it is a Cantor set. It is easy to see that the restriction of a double rotation…

Energy-based modeling, simulation, and control. Mathematical theory and algorithms for the solution of real-world problems – Volker Mehrmann (Technische Universität Berlin)
Energy based modeling via port-Hamiltonian systems is a relatively new paradigm in all areas of science and engineering. These systems have wonderful mathematical properties, concerning their analytic, geometric and algebraic properties, but also…
Come la matematica ha trasformato la vulcanologia da scienza qualitativa a scienza quantitativa – Mattia de' Michieli Vitturi (Istituto Nazionale di Geofisica e Vulcanologia)
Negli ultimi decenni la vulcanologia si è profondamente trasformata e grazie alla matematica, alla fisica, alla statistica oggi è diventata…
Il prezzo non è mai giusto, ovvero perché la finanza ha sempre bisogno di matematici – Luca Caputo (Banco Santander)
Per ideare e implementare i modelli matematici necessari per determinare il prezzo corretto dei derivati e valutare il rischio in…
Fourier Rearrangement: Symmetry results for PDEs of arbitrary order – Enno Lenzmann (University of Basel)
In this talk, I will give an introduction to the method of Fourier rearrangements. This is a new method for proving optimal symmetry results for minimizers of variational problems involving (pseudo-)differential operators. In particular, we can…
Motilità biologica e robot bio-ispirati: nuove sfide e opportunità e per la matematica – Antonio DeSimone (Scuola Superiore Sant’Anna)
La biologia è una ricca fonte di ispirazione, anche per la ricerca di nuovi materiali, nuove forme e strategie di movimento, dispositivi mobili e adattabili con nuove funzionalità, strutture architettoniche biomorfe. Di straordinario interesse sono…
Polynomial mixing time for edge flips on planar maps – Alessandra Caraceni (University of Oxford)
A long-standing problem proposed by David Aldous consists in giving a sharp upper bound for the mixing time of the so-called “triangulation walk”, a Markov chain defined on the set of all possible triangulations of the regular n-gon. A single step…
Cutoff thermalization for Ornstein-Uhlenbeck systems with small Lévy noise in the Wasserstein distance – Michael Högele (Universidad de los Andes)
This talk presents recent results on cutoff thermalization (also known as the cutoff phenomenon) for a general class of asymptotically exponentially stable Ornstein-Uhlenbeck systems under ε-small additive Lévy noise. The driving noise processes…
Piecewise affine homeomorphisms of the circle and dilation surfaces – Selim Ghazouani (Université d’Orsay, France)
In this talk I will consider the following question: if one picks a piecewise affine map of the circle “at random”, what dynamical behaviour are we likely to observe? The case of standard circle diffeomorphisms has been studied by Herman in the 80s;…
(Fractional) random Schrödinger operators, integrated density of states and localization – Constanza Rojas-Molina (CY Cergy Paris Université)
In this talk we will review some recent results on random Schrödinger operators, which are used to model electronic transport in disordered quantum systems and to study the phenomenon of Anderson localization. After a short introduction to the…
