Abstract: For 0<α<, Nα is the class of meromorphic
functions f defined in the unit disk D satisfying supzD(1|z|2)αf#(z)<, where f#(z)=|f(z)|/(1+|f(z)|2). Some new characterizations of the α-normal functions are given for 0<α<1. Characterizations are given in terms of the Bergman-Carleson measure conditions and the compact Bergman-Carleson conditions.

Key words: α-Normal functions, Normal functions, Meromorphic functions, Spherical derivative, Pseudohyperbolic disk
