Title: The Erdõs discrepancy problem.

Abstract: The discrepancy of a sequence $$f(1), f(2), \ldots$$ of numbers is defined to be the largest value of $$|f(d) + f(2d) + \ldots + f(nd)|$$ as $$n,d$$ range over the natural numbers. In the 1930s, Erd\"os posed the question of whether any sequence consisting only of $$+1$$ and $$-1$$ could have bounded discrepancy. In 2010, the collaborative Polymath5 project showed (among other things) that the problem could be effectively reduced to a problem involving completely multiplicative sequences. Finally, using recent breakthroughs in the asymptotics of completely multiplicative sequences by Matomaki and Radziwill, as well as a surprising application of the Shannon entropy inequalities, the Erdõs discrepancy problem was solved in 2015. In this talk I will discuss this solution and its connection to the Chowla and Elliott conjectures in number theory.
