Title: **Introduction to dynamical systems **(3CFU)

Teacher: Anna Miriam Benini

Syllabus: *We will introduce the basic concepts of discrete dynamical systems, that is, systems generated by the iteration of a map on a space with appropriate regularity properties. We will consider circle rotations, symbolic dynamical systems, smooth maps of $R^2$ , and we will conclude with a brief class in complex dynamics. In these cases, and in general, we will study invariant sets (equilibrium state), the basics of ergodic theory like invariant probability measures and topological entropy, and if possibile structural stability and related topics. We will cover selected topics in Chapters 1-6 from A. Katok, B. Hasselblatt, "Introduction to the Modern Theory of Dynamical systems"*.

Dates 2020/2021: The course will take place in the spring semester 2021. There will be 20-30 hours of lectures and the final exam will be a seminar given by the student on a topic inherent to the course.

Title: **Intuition, conceptualization and formalization in mathematics teaching and learning **(3CFU)

Teacher: Laura Branchetti

Syllabus: *Procedures, concepts, objects, symbols: the complex relationship between epistemic and cognitive meaning in mathematics teaching and learning Intuition in Mathematics and Figural concepts. Concept image and concept definitions.*

Lectures involve: Boundary integral formulation of elliptic, parabolic and hyperbolic problems - Integral operators with weakly singular, strongly singular and hyper-singular kernels - Approximation techniques: collocation and Galerkin BEMs - Quadrature formulas for weakly singular integrals, Cauchy principal value integrals and Hadamard finite part integrals - Convergence results - Numerical schemes for the generation of the linear system coming from Galerkin BEM discretization. Knowledge of basic notions in Numerical Analysis and in particular in numerical approximation of partial differential equations is required. References will be provided directly during the course.*

Title:** Constraint Satisfaction Problems** (4CFU)

Teachers: Federico Bergenti

Syllabus: *The course is intended to provide an introduction to the current research on Constraint Satisfaction Problems (CSPs) to students with no specific background in Computer Science or Artificial Intelligence. The course starts with an introduction to CSPs and with an overview of algorithms for constraint satisfaction based on heuristic search. Then, algorithms for constraint propagation are presented (e.g., arc consistency and hyper-arc consistency), and the forms of consistency that they achieve are discussed. Finally, algorithms to treat polynomial constraints are shown (e.g., Buchberger's algorithm and cylindrical algebraic decomposition), with emphasis on polynomial constraints over finite domains (e.g., based on Bernstein polynomials and on Rivlin's bound).*

Dates 2020/2021: 8-10 hours in November-December 2020 (flexible).

Title: **Extended kinetic theory and recent applications** (4CFU)

Teachers: Marzia Bisi, Maria Groppi

Possible list of topics: distribution function and Boltzmann equation for a single gas: collision operator, collision invariants, Maxwellian equilibrium distributions; entropy functionals and second law of thermodynamics; hydrodynamic limit, Euler and Navier-Stokes equations; kinetic theory for gas mixtures: extended Boltzmann equations and BGK models; kinetic models for reacting and/or polyatomic particles; Boltzmann and Fokker-Planck equations for socio-economic phenomena, as wealth distribution or opin-ion formation.*

The second part will focus on developing the necessary tools to study the geometry of Nakajima quiver varieties and the structure of their equivariant cohomology. Finally, in the last part, these two aspects will come together, showing the natural appearance of Yangians in the context of algebraic geometry, following the approach of Maulik-Okounkov which led to the discovery of a new kind of Yangians.*
