Department Assembly  November 28, 3:30 pm, lecture room M1 


The autumn Department Assembly will meet on Wednesday, November 28, at 3:30pm, lecture room M1.
The programme involves three main points: brief report on the development of the department (J. Slovak), information about the passage to newly accredited programmes of study (J. Paseka), and presentation of the PR and popularization activities at our department (P. Zemanek).
The assembly will be chaired by P. Hasil.

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 GelfandFuchs cohomology are considered. Sufficient conditions for nontriviality in terms of the dynamical properties of generators of the holonomy groups are found. The nontriviality for the Reeb foliation is shown; this is in contrast with some classical theorems on the GodbillonVey class, e.g, the MizutaniMoritaTsuboi Theorem about triviality of the GodbillonVey 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.
