PhD in Mathematics 37th cycle

(PhD Mathematics) Home | Program | Faculty PhD Students

Lectures take place at “Dipartimento di Scienze Matematiche, Fisiche e Informatiche”, Mathematics Building, Parco Area delle Scienze 53/A, 43124 Parma (location). 


Title and Credits: Numerical methods for Boundary Integral Equations, 6 CFU
Teacher: Alessandra Aimi

Syllabus: The course is principally focused on Boundary Element Methods (BEMs).
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.

Dates 2021/2022: Lectures will take place in Spring 2022 at the University of Parma for an amount of 24 hours. 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 quantum groups, 4CFU
Teacher: Andrea Appel

Syllabus: The course will be a blend of mostly representation theory (quantum groups and Hopf algebras), a bit of basic complex algebraic geometry (blowups), some category theory (braided monoidal categories), and some deformation theory (Hochschild cohomology). The course is intended for a general mathematical audience: I will do everything from scratch, assuming only the basic notions in algebra and geometry.

The first part of the course will provide a parallel between the classical theory of the Lie algebra sl(2) and that of its quantum counterpart Uqsl(2), with a special focus on the role of the universal R-matrix and the Yang-Baxter equation.

The topics discussed in the second part of the course will depend upon the main interests of the audience. Potential topics are: monodromy of the Knizhnick-Zamoldchikov equations and Kohno-Drinfeld theorem; Yangians and quantum loop algebras; Etingof-Kazhdan quantization of Lie bialgebras; categorification and Khovanov-Lauda-Rouquier algebras; Reshetikhin-Turaev invariants; quantum groups at root of unity
