Title and Credits: Geometry of principal frequencies (4 CFU)
Teacher: Lorenzo Brasco
Syllabus: 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.
Dates 2023/24: the precise dates will be decided together with the interested PhD students, who are encouraged to contact the teacher in advance.
Title and Credits: Introduction to mathematical fuzzy logic (2 CFU)
Teacher: Carles Noguera
Syllabus: Originating as an attempt to provide solid logical foundations for fuzzy set theory,and motivated also by philosophical and computational problems of vagueness and imprecision, mathematical fuzzy logic (MFL) has become a significant subfield of mathematical logic. Research in this area focuses on many-valued logics with linearly ordered truth theories and challenging problems, thus continuing to attract an ever increasing number of researchers. The goal of this course is to provide an up-to-date introduction to MFL. Starting with the motivations and historical origins of the area, we present MFL, its main methods, and its core agenda. In particular, we focus on some of its better known logic systems ( Lukasiewicz and Godel–Dummett logics, BL, MTL) and present a general theory of fuzzy logics. Finally, we give an overview of several currently active lines of research in the development and application of fuzzy logics.
Dates : 1-5 July 2024, lectures of 2 hours from Monday to Friday .

Title and Credits: An introduction to uncertainty quantification for PDEs (4 CFU)
Teacher: Giulia Bertaglia, Elisa Iacomini
Dates: June 2024, 10h lectures + reading course + home assignments
Title and Credits: Embodiment, Discourse and Technology in Mathematics Education Research (4 CFU + 2 CFU optional, for some research work)
Coordinator: Federica Ferretti
Syllabus: The aim of the course will be to acquire specific knowledge - and their use in research practices - of some of the most internationally popular theoretical frameworks in mathematics education. There will be plenary sessions, led by Ferdinando Arzarello (University of Turin), Paul Drijvers (Utrecht University), Anna Sfard (University of Haifa) and Osama Swidan (Ben-Gurion University of Negev), a round table discussion led by Ornella Robutti (University of Turin) and workshops - held by Federica Ferretti and other Italian researchers - in which doctoral students will be able to engage with the theoretical lenses discussed.

Title: internet Seminar on Harmonic Analysis (ISEM27), edition 27
Dates: october 2023- february 2024, local coordinator Prof. Michele Miranda
At the end of the course (project phase (3CFU)), in-depth topics are proposed. Small groups of students from different universities are formed with the aim to study these topics and prepare a communication for the Final Workshop to be held in Luminy (Marseille, France).
