Yaroslav Bazaikin:

Losik classes for codimension one foliations

Abstract:

This is a joint work with A. Galaev. Following Losik's  approach to Gelfand formal geometry, certain characteristic classes  for codimension one foliations coming from Gelfand-Fuchs cohomology are considered. Sufficient conditions for non-triviality  in terms of the dynamical properties of generators of the holonomy groups are found. The non-triviality for the Reeb foliation is shown; this is in contrast with some classical theorems on the Godbillon-Vey class, e.g, the Mizutani-Morita-Tsuboi Theorem about triviality of the Godbillon-Vey class of foliations almost without holonomy is not true for the classes under consideration. It is shown that the considered classes are trivial for a large class of foliations without holonomy. The question of triviality is related to ergodic theory of dynamical systems on the circle and to the problem of smooth conjugacy of local diffeomorphisms. Certain classes are obstructions for the existence of  transverse affine and projective connections.

19th mathematical hike - November 24th 2018 PDF Print

You are cordially invited to our 19th mathematical hike that will take place on November 24th.

Start at 08:54 in front of the train station in Břeclav. You can join us in Brno taking train EC (departure at 08:23).

We have planned a 20 km hike starting in Břeclav going south visiting palaces Pohansko and Lány in a riparian forest near the borders of three countries.

We look forward to seeing you.

Jana Bartoňová and Jonatan Kolegar, organizers

Innolec lectures - Gian Maria Dall'Ara - An invitation to PDE methods in several complex variables PDF Print

Innolec lectures from 5.11.18 - 8.11.18

The first lecture will take place on Monday, 12:00-14:00, in the Seminar room on the 1st floor.

 

Gian Maria Dall'Ara (University of Vienna)

An invitation to PDE methods in several complex variables

Abstract:

In these lectures I will present the point of view on complex analysis in several variables originated in the '60s from the seminal work of Hörmander and Kohn (among others) on the d-bar problem and some of the most interesting applications. A tentative list of the topics I will discuss is:

1) one versus several complex variables: domains of holomorphy and failure of Riemann mapping theorem;

2) the problem of smooth extension to the boundary of biholomorphisms (Fefferman and Bell-Ligocka theorems);

3) existence and compactness in the d-bar problem: a review of some ideas of Hörmander, Kohn and Catlin;

4) Kohn-Nirenberg regularity and recent work on necessary and sufficient conditions for compactness.

The lectures will be suited (and hopefully interesting) for master students and researchers alike.
