Linear ODEs in the complex domain and isomonodromy deformations

The aim of the course is to introduce the audience to linear systems of differential equations in the complex domain, their monodromy and essential monodromy data. Then, the theory of isomonodromy deformations will be studied, with applications to some examples. These notions play an important role in modern mathematical physics, for example in integrable systems.
  •     Existence and uniqueness theorems in the complex domain.
  •     Linear systems
  •     Singularities and monodromy

Integrable systems

Integrable systems are special  systems which can be solved exactly in some sense. They arise in a variety of settings, ranging from Hamiltonian systems, nonlinear wave equations   and probability. This  course covers the origins of the subject as well as modern topics in  nonlinear waves  and  integrable probability.

1.  The Korteweg de Vries equation (KdV) 

Self-adjoint operators in quantum mechanics

The course will give an overview on the operator-theoretical tools needed for a rigorous formalization and treatment of a quantum mechanical model with special emphasis on unbounded self-adjoint operators.

Topics:

Hamiltonian methods for integrable systems

The course is centered on the Hamiltonian aspects of integrable systems of Ordinary and, especially, Partial Differential Equations, with a focus on the geometrical side.

Integrability will mean

Existence of a “sufficient number” of conservation laws.

Contents & schedule

Intersection theory

The course is 60 hours, but it has a natural division into 40+20 so it makes sense to attend only the first part.It will take place starting in the second half of November and will finish at the end of March.

Noncommutative geometry

 
I will focus on the latest layer Riemannian and Spin of Noncommutative Geometry (NCG). Its central concept, due to A. Connes, is 'spectral triple' which consists of an algebra of operators on a Hilbert space and an analogue of the Dirac operator.
 

Topics in advanced algebra

An introduction to the theory of derived functors in homological algebra, and its applications to sheaves and other geometric and algebraic objects.
  • Basic notions: categories, functors, abelian categories, complexes
  • Derived functors: injective objects, right derived functors, long exact sequence of a derived functor, acyclic resolutions, delta-functors.
  • Introduction to sheaves: presheaves, sheaves, étalé space, direct and inverse images
