Witt Vectors and a Question of Entin, Keating, and Rudnick

This is Part II of the paper "Witt vectors and a question of Keating and Rudnick" [6]. Here, we prove an independence result for tuples of character sums, formed with a variable character and its powers. In the Appendix, we prove an independence result for tuples of character sums formed with variable pairs of characters and products of the two.
