Math. 59 (1937). 2) The case n=2 is the well known theorems of Fatou and Schwarz. For the case n=3 I have proved analogous theorems in a paper: On Fatou's theorem on Poisson integrals. Jap. Jour-Math. 15 (1938). The method can be applied for the general case. 3) Osgood: Lehrbuch d. Funktionentheorie IIJ. p. 191 4) Bochner: Functions of several complex variables (1936) p. 194. Lemma,
