ABSTRACT
The weight functions WA(z) and ws(z), associated with {Am(z)}~=O and {Bm(z)}~=o on the interval ( -oo, 0), respectively, are the following (defined on all of Ill). Definition 14.1 For z E Ill, let
(14.1)
and
(14.2)
The fact that ( -oo, 0] is the orthogonality interval and the relationships in (13.5) and (13.6) imply that the zeros of 6n(x) are pure imaginary.
