Abstract
We consider exponential polynomials with restricted coefficients, for example by requiring that they all have absolute value 1, or the even more restricted class considered by Littlewood, namely those whose coefficients are all \(\pm 1\). This paper expands on material presented in the Erdős Colloquium delivered on March 18, 2016, as part of the 2016 Gainesville International Number Theory Conference.
This paper is dedicated to Krishnaswami Alladi on the occasion of his 60th birthday
