D. Alpay et V. Bolotnikov, ON A CLASS OF FUNCTIONS ANALYTIC IN A HALF DISK AND AN ASSOCIATED INTERPOLATION PROBLEM, Journal of mathematical analysis and applications, 182(1), 1994, pp. 1-22
In this paper we introduce a class of functions analytic in a half dis
k and for which the Nevanlinna-Pick interpolation problem has a soluti
on in terms of a linear fractional transformation. The method used to
solve this problem is that of the fundamental matrix inequality, suita
bly adapted to the present situation. (C) 1994 Academic Press, Inc.
