10. Proof of Proposition 2.4

The goal of this section is to prove Proposition 2.4. We continue to assume 1 ≤ j ≤ 3.

By Lemma 8.1 we have

The contour of integration is moved in the same way as the proof of Lemma 8.1. Thus, by Lemma 5.8 and 8.2,

This yields (10.8) since the function

Thus, with simple modification, Lemma 10.1 and 10.2 apply to the sums

Noting that

and gathering the above results together we conclude

with

Hence, by Proposition 7.1,
