Intensive-course on "Spaces of Entire Functions in Spectral Problems" by Alexei Poltoratskin

Alexei Poltoratskin (Texas A&M University)
will lecture a one week course

Timetable

Tuesday 13.11. 14-16 D122
Wednesday 14.11. 14-16 D123
Thursday 15.11. 14-16 D122
Friday 16.11 14-16 C124

Abstract:

The Krein - de Branges theory of Hilbert spaces of entire functions was introduced around mid 20th century to treat spectral problems related to differential operators and canonical systems.
Since then, the theory has become a fundamental part of spectral and complex analysis. It was applied in numerous important problems, e.g. Marchenko's proof of the uniqueness of the inverse spectral problem for Schroedinger operators. The course covers the basics of the theory, its connections with other branches of complex and harmonic analysis and recent applications.

Biomathematics Day 9

A full-day biomathematics seminar on Wednesday 14 May 2012, in Kumpula, Exactum. Program and venue: pdf. Registration by email to eva.kisdi@helsinki.fi.

Intensive-course on "Fluctuation relations in stochastic thermodynamics" by Krzysztof Gawędzki

Krzysztof Gawędzki (Laboratoire de Physique ENS de Lyon)
will lecture a one week course

Timetable

Mon 05.11 at 14 in D122, Lecture 1 : Transient fluctuation relations for Markov processes.
Tue 06.11 at 14 in D122, Lecture 2: 2nd Law of Stochastic Thermodynamics.
Thr 08.11 at 14 in D122, Lecture 3: Fluctuation-dissipation relations.
Fri 09.11 at 14 in CK107,Lecture 4: Stationary fluctuation relations for large deviations.

Abstract:

Nonequilibrium statistical mechanics aims at a statistical description of closed and open
dynamical systems of large dimension. Fluctuation relations are robust identities concerning
the statistics of entropy production or performed work in such systems. They are expected to
hold arbitrarily far from thermal equilibrium.
The lectures present a self contained mathematical introduction to fluctuation relations in the
setup of finite-dimensional diffusion processes.

Weak and strong disorder in directed polymer models

Introduction to the d+1 dimensional directed polymer model (warning: no connection with polymer physics!). Martingale techniques for proving a central limit theorem in high temperature and localization in the so-called strong coupling regime (low temperature or d=1,2). The expected KPZ behavior in 1+1 dimensions.

Lecture 2. 10.1. 2012 14-16.

The Burke property in M/M/1 queues and directed polymer models

Crash-course on "This sets and convolutions" by Tom Körner

Tom Körner (Cambridge University)
will visit the mathematics department of the University of Helsinki
Weeks 37 and 38 and will lecture the crash course

"This sets and convolutions"

Abstract:
We know that if we convolve a function with itself
the result is smoother. But how much smoother can
it be? I shall develop the the tools from Fourier
analysis and probability theory which enable us to attack
this problem. We shall also look at, more or less,
related problems on Hausdorff dimension and
sets of multiplicity.

Time and Place

Lectures: B120 Mon-Thu 10-12 and D123 Fri 10-12
Computer labs: C128 Mon-Wed and Fri 13-14, Thu 15-16

This intensive course presents modern numerical methods and software for bifurcation analysis of parameter-dependent systems of smooth autonomous ordinary differential equations (ODEs). The main problems are: How to continue equilibria and periodic orbits with respect to a parameter? How to compute stability boundaries of equilibria and periodic orbits (limit cycles) in the parameter space? How to predict qualitative changes in system's behavior (bifurcations) occurring at these boundaries? How to locate and continue homoclinic orbits to equilibria? Only the most efficient methods will be described, which are based on projection and bordering techniques and employ boundary value problems (BVPs). These methods have been recently implemented in MATCONT, an interactive MATLAB bifurcation software for ODEs. An integral part of the course are computer sessions at which the students will learn how to use the latest version of MATCONT. No preliminary knowledge of bifurcation theory is assumed.

"An Introduction to Non-Homogeneous Harmonic Analysis"

Time and Place

th 21.10 12-14

all lectures in B120 Exactum Building

Course abstract:
Non-Homogeneous Harmonic Analysis concerns classical operators T, like Maximal Function or Hilbert transform,
but studied on weighted spaces. The goal is to characterize those pairs of weights (u,v) for which T maps L^2(u) to L^2(v).
Such questions occur naturally in a variety of settings, from analytic function spaces, to quasiconformal maps.
For positive operators, like the Maximal Function, Fractional integrals, or Poisson integral, there is a complete theory.
For the Hilbert transform, we have incomplete information, which nevertheless still contains beautiful results.

We will start from the beginning, with a special emphasis on dyadic methods.

General information on courses and seminars

Basic courses

The dynamical systems course that has been taught by the mathematical physicists will be made a basic course common to all and taught every year. It will serve as a springboard for the evolutionary dynamics courses, for courses in extended dynamics and complex dynamics as well as for geometric measure theory courses.

We will also organize interdisciplinary courses in physics and biology on the graduate level and plan to have some biology courses aimed for mathematicians in the same vein.

Intensive courses

Intensive courses will be given by outstanding professors invited from abroad as well as by the professors of the CoE themselves. Such courses have proved to be very effective. We shall also continue the successful practice of holding some of our research workshops in connection with the Jyväskylä Summer School. The following courses are already planned:

  • Stochastic aspects of complex dynamics (M. Zinsmeister)
  • Statistical turbulence: from numerical simulations to renormalization group analysis (A. Mazzino)
  • Evolutionary dynamics through bifurcation analysis: methods and applications (F. Dercole)

The biomathematics group organized a bi-annual series of international schools in 2008, 2010 and 2012 on the topic of mathematical ecology and adaptive dynamics, each lasting 5 days. The title of the series will be "The Helsinki Summer School on Mathematical Ecology and Evolution".

Seminars

The CoE will organize a series of weekly seminars that is to be attended by all our graduate students and post-docs, who will also give presentations themselves to improve their communication skills. Our students are also encouraged to attend the frequent seminars given by visitors to our departments.

Workshops

The CoE will organize two kinds of workshops:

1. Full-day seminars that cover the current activity of the CoE. These will introduce our students and post-docs to the full spectrum of our research, and help to exploit all collaborative possibilities within the CoE.
2. International workshops dedicated to particular research topics in January 2009, 2011, and 2013. These will last typically 3-5 days and have 20-30 participants, about two-thirds of them from abroad.
