Anna Benini

Summary: Anna Miriam Benini introduced topics such as conformal mappings, Riemann surfaces, Riemann mapping theorem, classification of Riemann surfaces, and meromorphic functions on the Riemann sphere.

Gabriele Benedetti

Charlene Kalle

Summary: A comprehensive review on Banach and Hilbert spaces, covering foundational concepts and structural properties essential to understanding these spaces. In addition, we presented major theorems in functional analysis, including the Hahn-Banach Theorem, Banach-Steinhaus Theorem, and Riesz Representation Theorem, explaining their implications and applications. All lectures were accompanied by tutorial sessions, a homework was given to be sent by email by students.
 

Peter Stevenhagen

Summary: This is part of the regular International Master in Mathematics program.
 

Krerley Oliveira

Summary:  I covered the section of the course related to methods for computing and estimating eigenvalues and eigenvectors. My focus was on the foundational aspects of this theory, including classic theorems and methodologies. Several examples were thoroughly discussed with the students. I placed particular emphasis on class discussions and practical exercises, which included hands-on activities and a set of homework assignments.
 

Etienne Pardoux

Summary:  I will treat conditional expectation, uniform integrability tightness, and convergence in law. The exact content will depend upon how reactive the students are. I will give them exercises along the way.

 

Frank Neumann

Samuël Borza

Summary:  Theory of distributions, sub-Riemannian structures, and admissible trajectory, controllability and Chow-Rachevsky theorem, Cauchy-Carathéodory theorem and the endpoint map, necessary conditions for minimality (Pontryagin’s Maximum Principle, normal and abnormal extremals), the Heisenberg group, the Grushin plane, the Martinet flat structure, contact structures, and Carnot groups, metric tangent for sub-Riemannian structures.
 

Wilhelm Klingenberg

Summary:  Necessary background in analysis (density functions and its push forward by a map of domains, convexity and the second derivative condition, Legendre transform, convex dual of a functional, and Jensen’s inequality), Monge minimization problem of transport for a continuous cost function c(x, y) with an example in one space dimension, the dual maximization problem due to Leonid Kantorovich, Brenier Theorem.
 

Mark Rudelson

Summary:  Wigner Semicircle Law for normalized eigenvalues of large random symmetric matrices was proved, which can be viewed as a non-commutative version of the Central Limit Theorem. For this purpose the following technical tools were introduced and developed: Stieltjes transform, Hanson-Wright inequality, self-consistent equation for Stieltjes transform.
