Abstract. We present some background and also recent advances due to J. Bourgain, K. Ford, S. Konyagin and the speaker.
These new results are based on a combination of various techniques including the distribution of smooth numbers, distribution of elements of multiplicative subgroups of residue rings, bound of Heilbronn exponential sums and a large sieve inequality with square moduli. These techniques will be briefly explained as well.
