Igor Uljarević (University of Belgrade)Size in contact geometry

In this talk, I will cover the basics of contact manifolds – defining them and highlighting their main properties. I will discuss the concept of contact non-squeezing, a handy tool for understanding size when there is no natural measure or metric. Lastly, I will share an interesting finding: while contact geometry does not capture size of a ball on a small scale, it surprisingly does so on a larger scale in certain cases.
