Topics in Representation Theory (6 CFU) - Prof. A. Appel - January 29 : April 16, 2025

Teacher: Prof. Andrea Appel (andrea.appel@unipr.it)

Title: Topics in Representation Theory

Syllabus:  
 The Yang-Baxter equation (YBE) is a fundamental symmetry in mathematics and physics arising from a system of particles moving along a line. The quest for constant solutions of YBE (R-matrices) is at the very origin of the theory of Drinfeld-Jimbo quantum groups and their universal R-matrix. In this course, we will review the role and the importance of the YBE in various areas of algebra, geometry, and topology. I will explain the interplay between quantum groups and R-matrices in its simplest case. Then, I will outline some recent and novel construction of R-matrices depending on a spectral parameter in the case of a quantum group of “higher order” known as the Yangian.

Schedule of the course  (24 hours / 6CFU)

Dates: 29/01/205 - 16/04/2025  - Lectures will be held every Wednesday 1:30pm-3:30pm at the University of Parma (Room C, Mathematics Building). Simultaneously, lectures will be streamed on a dedicated MS Teams Channel for online participation (link). 

Note: At the request of participants, it is possible to attend the lessons online.

De Giorgi-Nash-Moser theory for fractional kinetic operators (5 CFU) - Dott.ssa F. Anceschi, Dott. M. Piccinini - November 8, 2024- January 20, 2025

Francesca Anceschi (f.anceschi@staff.univpm.it)
Mirco Piccinini (mirco.piccinini@dm.unipi.it)
Syllabus: 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 fractional
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 kinetic 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.

Introduction to Design Theory (7 CFU) - Prof.ssa A. Pasotti, Prof. T. Traetta - February 10, 2025 - March 2025

Introduction to Design Theory (28 hours, 7 CFU, Anita Pasotti, Tommaso Traetta)

This course aims to introduce some of the fundamental concepts in the area of design theory such as block designs, graph decompositions, difference families, and present some modern extensions of this subject.
Dates: February- March 2025. Precise dates will be decided together with the interested PhD students, who are invited to contact the teachers by January 20th to define the calendar.
The course will be held online on Microsoft Teams.
Students are required to present an in-depth study of approximately 20 minutes on a topic of the course.

The quasi-Hopf analogue of the Drinfeld-Jimbo quantum groups (2 CFU) (onsite and online). Prof. Daniel Bulacu - September 11-12-17-19 2024.

Title and Credits: Galois Theory: from groups and forms to descent theory and extensions

Teacher: Prof. Daniel Bulacu, University of Bucarest

Syllabus:  The classical Galois theory dates back to 1830, but it took more than 100 years for it to be reformulated (by Artin) in the language of module theory. Artin's criterion that decides when a field extension K/k is Galois allows to extend the classical Galois theory to Hopf algebras. This was initiated by Chase and Sweedler in 1969 in the commutative case, the general case being considered by Kreimer and Takeuchi in 1981. Today Hopf-Galois extensions appear in various branches of mathematics and physics, being also known as dual algebraic versions of non-commutative fiber spaces (the notion of quantum fiber space can be introduced as a module associated with a Hopf-Galois extension).

The purpose of this course is to make the transition from the classical Galois theory to the Hopf-Galois theory and to present some directions of study for the latter. Briefly, the content of the course is as follows:

  • Classical Galois theory.
  • Extensions of fields, extensions of separable Galois fields without groups, strongly graded rings, cross products, affine group schemes.
  • Relevant examples of Hopf algebras.
  • Hopf-Galois extensions and examples.
  • Descent theory.
  • Hopf-Galois theories in various categories.

Dates 2022/2023: 4, 6, 11, and 13 July 2023, 16:00-18:00 (4 lectures, 8 hours).
