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.

Seminar of differential equations will continue on November 19, 2018 at 12pm in lecture room M5.

Evolutionary games with time constraints

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.
