On Bilinear Exponential and Character Sums with Reciprocals of Polynomials
We give nontrivial bounds for the bilinear sums where
is a nontrivial additive character of the prime finite
field of elements, with integers , , a polynomial
and some complex weights ,
. In particular, for we obtain new bounds of bilinear
sums with Kloosterman fractions. We also obtain new bounds for similar sums
with multiplicative characters of
