12. Evaluation of Ξ15

In a way similar to the proof of Lemma 8.4, by lemma 8.2 and 5.8, we find that the right side above is equal to

It follows by Cauchy’ integral formula that

Gathering these results together we obtain (12.10). The proof of (12.11) is similar to that of.

Proof. The left side is equal to

Assume |w| = α. In a way similar to the proof of Lemma 12.1, we deduce that

By direct calculation,

and the derivative of

at w = 0 is equal to

This can be written as the form

Since

it follows by simple calculation that

We have
