DIDATTICA

Programma: This is 4/5 weeks 18 hours PhD course from a visiting professor. This course offers a foundational introduction to differential geometry, focusing on manifolds, submanifolds, and key examples like Lie groups, projective spaces, and Grassmannians. It covers tensors, exterior calculus, differential forms, and their roles in vector fields, symplectic manifolds, and Hamiltonian mechanics. Stokes’ Theorem, orientation, and manifolds with boundary are explored in depth. Students learn about vector bundles, connections, curvature, and Riemannian geometry, including Gaussian curvature and the Levi-Civita connection. The course introduces distributions, foliations, and Frobenius’ theorem, then moves into the structure of Lie groups and algebras, with applications to classical matrix groups. It delves into the geometry of surfaces in homogeneous spaces using Cartan’s method and the Darboux derivative. The concept of G-structures is introduced, along with examples like almost complex and symplectic structures. If time allows, the Gauss-Bonnet theorem and its extension via Chern-Weil theory are also covered.

Programma: The main goal of this course is to provide a useful toolbox for the study of the weak regularity theory á la De Giorgi-Nash-Moser (DGNM) for local and nonlocal kinetic operators. Firstly, we will analyze the local case of the Fokker-Planck operator in order to introduce the non-Euclidean geometry required for the study of these operators. Then, we will provide all the advanced necessary tools to deal with the nonlocal case, and we will conclude the course with some interesting applications to more complex physical models, as e.g. those involving the Boltzmann operator, where the main diffusion non-symmetric kernel satisfies very weak integrability and non-degeneracy conditions.

Programma: The first part of the course will provide an introduction to complex and almost complex geometry. There will be a concise overview of the theory of holomorphic functions of several complex variables, omitting analytical details, leading to basic examples of complex and almost complex manifolds. We will also discuss the Dolbeault, Bott-Chern and Aeppli cohomologies. The second part of the course will focus on the Hermitian geometry, starting with the Kaehler manifold and describing their cohomological properties. Then, the existence of special structures on compact complex manifolds and their deformations will be investigated. Explicit examples and computational techniques of cohomological invariants will be carefully described.

Notes for the course will be provided.

Programma: This course focuses on the mathematical and physical principles governing fluid flow through porous media, an essential topic in many fields such as hydrology, biology, and environmental science. In particular, the course will explore the concept of asymptotic homogenization, a method used to derive effective macroscopic models that describe the behavior of fluid flow through heterogeneous media on the microscopic scale.

Fluid flow in porous media is inherently complex due to the spatial heterogeneities present in the medium. Asymptotic homogenization provides a systematic approach for averaging the microscale properties of the medium to derive a simpler, yet accurate, macroscopic model. This course will lay down the mathematical foundations of fluid flow in porous media, introduce the theory of asymptotic homogenization, prove key results, and show how these results lead to effective models for real-world applications. Some prerequisites of fluid dynamics will be recovered at the beginning of the course.

Programma: The first eigenvalue of the Laplacian on an open set, and more generally of a second order elliptic operator, is an important object both from an applied and theoretical point of view. In Mathematical Physics, it usually plays the role of the ground state energy of a physical system. Despite its importance, for general sets it is not easy to explicitly compute it: thus, we aim at finding estimates in terms of simple geometric quantities of the sets, which are the sharpest possible. The most celebrated instance of this kind of problems is the so-called Faber-Krahn inequality. This course offers an overview of the methods and results on sharp geometric estimates for the first eigenvalue of the Laplacian and more generally of sharp Poincaré-Sobolev embedding constants (sometimes called “generalized principal frequencies”). In particular, we will present: supersolutions methods, symmetrization techniques, convex duality methods, the method of interior parallels, conformal transplantation techniques.

Programma: Lie algebras are algebraic structures with wide-ranging applications in geometry and mathematical physics. The course will focus on semisimple Lie algebras and their real forms, addressing their structure and classification. We will introduce the fundamental concept of root systems and study finite reflection groups associated with them, i.e. the Weyl groups. These combinatorial tools will be used to classify semisimple Lie algebras and their real forms, classical and exceptional cases.

Referenze bibliografiche: The primary reference for this course will be J.E. Humphreys’ book Introduction to Lie Algebras and Representation Theory. Additionally, Anthony W. Knapp’s book Lie Groups Beyond an Introduction will serve as a helpful supplementary resource.

Programma: Symbolic learning is the sub-discipline of machine learning that is focused on symbolic (that is, logic-based) methods. As such, it contributes to the foundations of modern Artificial Intelligence. Symbolic learning is usually based on propositional logic, and in part, on first-order logic. Modal symbolic learning is the extension of symbolic learning to modal (and therefore, temporal, spatial, spatio-temporal) logics, and it deals with dimensional data. In this course we shall lay down the logical foundations of symbolic learning, prove some basic properties, and present the modal extensions of classical learning algorithms, highlighting which ones of those properties are preserved, and which ones are not.

Programma: The purpose of this course is to show how the non-linear analysis of structural elements subject to external actions cannot be reduced to simply checking a box on a drop-down menu in a commercial software such as Abaqus. Far from being exhaustive, I intend to present the basic principles that make it possible to acquire, at least, the nomenclature commonly used in non-linear structural mechanics. I hope that, after attending the course, the student will be able to make a more conscious use of the great computing capacities available today which, unfortunately, are too often abused. The topics that will be covered are summarized below.

Preliminaries. Euclidean space, points, vectors, tensors. Scalar product of vectors. Tensor product. Trace operator. Inverse of a tensor. Orthogonal tensors. Rotations. Oriented area and cross product of vectors. Volume and triple product of vectors. Determinant of a tensor. Symmetric and skew tensors. Green Theorem and transformation of surface integrals in volume integrals.

Analysis of the deformation. Actual and deformed configuration. Deformations defined by mappings. Homogeneous deformation. Pure deformations. Rotations. Polar decomposition theorem. Plane deformations. Infinitesimal deformations. 

Stress and balance laws. Forces. Contact forces. Euler separation axiom. Principle of local action. Simple materials. Cauchy’s theory and the definition of stress. Conservation of mass. Piola transformation. Balance of linear momentum. Balance of angular momentum. Cauchy stress tensor. First and second Piola-Kirchhoff stress tensors. 

Work of deformation. Work done by the external forces. Rate of change of kinetic energy. Work expended to deform the body. Work conjugation of the Cauchy, first and second Piola-Kirchhoff stress tensors, with the corresponding measures of deformations. 

Constitutive equations. General forms of the constitutive equations. Principle of determinism. Material frame indifference. Restrictions on the form of the equations. Correspondence with the molecular theory. Constitutive symmetries. Specialization to infinitesimal deformations.

Programma: The course will present classical and modern methods for studying Hölder regularity properties of solutions to elliptic partial differential equations. We will analyze, under a common geometric framework, two different approaches: a linear approach based on integral representations of the solutions, as well as a nonlinear approach mainly based on maximum principles. We will focus on 2nd order linear PDEs of uniformly elliptic type, and we will discuss the respective assumptions on the diffusion coefficients in order to trigger the two approaches.

Programma: Discrete event systems is an area that studies formal models like automata, Petri Nets, etc. that can be employed for the modeling, analysis, verification and synthesis of general systems like industrial plants. The need for control arises whenever a plant admits behaviors that are undesired and must be therefore prevented by control. Such problems are often due to the general-purpose design of the original system, the uncontrollability of some actions that can happen during execution or synchronization problems leading to a point of the execution where the system can no longer complete its tasks (blocking). Supervisory control is an area that provides tools and methodologies for the automatic synthesis of controllers for such systems. This course will provide an introduction to the subject by considering (extended) finite automata as the underlying formal model. The theoretical part will discuss supervisor synthesis algorithms. The applied part will go through the modeling of plants and safety requirements for some case studies as well as the concrete synthesis of controllers and the simulation of (controlled) plants by means of the state-of-the-art software ESCET (Eclipse Supervisory Control Engineering Toolkit) freely available here https://eclipse.dev/escet
