ABSTRACT
We intend to use Theorem 2.3i, part (i), to prove that Re p(z) > 0. This requires showing that condition (2.3-10) is satisfied. In this case (2.3-10) reduces to
Re 'lf(pi, a) s; 0, when p, a E JR and a s; _ I~- ip 12 2Re~ ·
(3.6-12) Re 'lf(pi, a) = Re _a_ + o = a -Re 'Y + 0 pi + 'Y I 'Y 12 + 2 p · Im r + p 2
where D > 0 and
C 2o·Re ~ - Re 'Y·
