“…The proofs follow in exactly the same manner, we will point out the main differences and provide the necessary asymptotics. Therefore as in [9] we can find w 1 (S, ξ) and w 2 (S, ξ) and since w 1 and w 2 are entire, by analyticity we can extend them to w 1 (S, ζ) and w 2 (S, ζ). 2) and m, the Titchmarsh-Weyl m-function for the same problem but with the potential q replaced by q.…”
