Character sum
text:
In mathematics, a character sum is a sum ∑ χ of values of a Dirichlet character χ modulo N, taken over a given range of values of n. Such sums are basic in a number of questions, for example in the distribution of quadratic residues, and in particular in the classical question of finding an upper bound for the least quadratic non-residue modulo N. Character sums are often closely linked to exponential sums by the Gauss sums. Assume χ is a non-principal Dirichlet character to the modulus N.
