Abstract

In [6], the author studied the property of the Szeg kernel and had a result that if <TEX>$\Omega$</TEX> is a smoothly bounded domain in C and the Szeg kernel associated with <TEX>$\Omega$</TEX> is rational, then any proper holomorphic map from <TEX>$\Omega$</TEX> to the unit disc U is rational. It leads to the study of the proper rational map of <TEX>$\Omega$</TEX> to U. In this note, first we simplify the proof of the above result and prove an existence theorem of a proper rational map. Before we proceed to state our result, we must recall some preliminary facts.(omitted)
