Title:Positivity in contact geometry
Seminar:Department of Mathematics Colloquium
Speaker:Peter Albers, University of Muenster, Germany
The notion of positivity in contact geometry was introduced in 2000 by Eliashberg and Polterovich. For example, geodesic flows (and more generally Reeb flows) are positive. This and other examples will be explained during the talk. Positivity has connections to many phenomena such as contact (non-)squeezing and biinvariant partial orders. Positivity leads to a generalization of the classical Bott-Samelson theorem and has connection to the famous Weinstein conjecture. Examples will be presented throughout the talk.
