Abstract: 

In the talk, which is joint work with Alexander Olevskii, I will present our study of the
relationship between the existence of arithmetic progressions with specified lengths and
step sizes and lower Riesz bounds of complex exponentials indexed by a set of integers
$\Lambda$ on subsets of the circle.
