Abstract:We prove that an analytic function f on the unit ball B with Hadamard gaps, that is, View the MathML source (the homogeneous polynomial expansion of f) satisfying nk+1/nk?λ>1 for all kN, belongs to the space View the MathML source if and only if View the MathML source. Moreover, we show that the following asymptotic relation holds View the MathML source. Also we prove that limr→1(1-r2)αRfrp=0 if and only if View the MathML source. These results confirm two conjectures from the following recent paper [S. Stevi?, On Bloch-type functions with Hadamard gaps, Abstr. Appl. Anal. 2007 (2007) 8 pages (Article ID 39176)].
