Omschrijving  Date: Tuesday, 20 March, 2018 Speaker: Dr. Jakub Byszewski (Jagiellonian University, Krakow) Room: 5161.0293 (Bernoulliborg) Time: 16.00  17.00 h Title: Sparse generalized polynomials and nilmanifolds
Abstract: We investigate generalised polynomials (i.e., polynomiallike expressions involving the use of the floor function) which take the value 0 at all integers except for a set of density 0. By a theorem of BergelsonLeibman, generalised polynomials can be completely described in terms of dynamics on nilmanifolds.
This is joint work with Jakub Konieczny (Jerusalem)
