Relations between fractal dimensions and arithmetic progressions

October 23 at 11:35 - 12:35, 2018

Mr. Kota Saito (Nagoya University)

In this talk we give estimates for the dimensions of sets in real numbers which uniformly avoid finite arithmetic progressions. More precisely, we say that $F$ uniformly avoids arithmetic progressions...more
