Query: Sums of multiplicative characters with additive convolutions   In the paper we obtain new estimates for binary and ternary sums of
multiplicative characters with additive convolutions of characteristic
functions of sets, having small additive doubling. In particular, we improve a
result of M.-C. Chang. The proof uses Croot-Sisask almost periodicity lemma.
