where R is an r × r matrix with 

Let us write det R as 

or equivalently as

Using this representation, we have

Since the contour K is chosen so that for any z ∈ K , Re z < ( ∑ r j =1 h$_{j}$ 1+ h$_{j}$ ) − 1 S, the integrand in the above multiple integral is absolutely integrable on [0 , ∞ ) × K × ... × K , and Fubini’s theorem justifies the interchange of the order of the integrals,
