is bounded on Hölder spaces and ( L^p ) ((1<p<\infty)). Find a sectionally analytic function ( \Phi(z) ) (vanishing at infinity as ( O(1/z) ) for the “exterior” problem) satisfying on ( \Gamma ):
with given Hölder-continuous ( G(t) \neq 0 ) and ( g(t) ). The of the problem is
with ( a(t), b(t) ) Hölder continuous. The key is to set
