Title: Trigonometric polynomials with multiplicative coefficients and small L^1 norms
Abstract: I will discuss joint work with Mayank Pandey in which we show that if a trigonometric polynomial has multiplicative coefficients and small L^1 norm then the coefficients have to be characters. One can view this as a variant of Littlewood's conjecture restricted to trigonometric polynomials with multiplicative coefficients.
