We introduce a new space, Q space, of analytic functions on the unit disk in T terms of a nondecreasing function T. The relation between Q and Q spaces, which have attracted considerable attention, is given by studying the growth order of T. The counterpart Q ࠻ of Q for the meromorphic case is also
Assuming hypothesis only on the -algebra F; we characterize (via Radon spaces) the class of measurable spaces ( ; F) that admits regular conditional probability for all probabilities on F.
## Abstract We define a class of weighted Besov spaces and we obtain a characterization of this class by means of an appropriate class of weighted Lipschitz __ϕ__ spaces. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
## Abstract In this paper we obtain new characterizations of the distributions in certain anisotropic Besov spaces associated with expansive matrices. Also, anisotropic Herz type spaces are considered and the Fourier transform is analyzed on anisotropic Besov and Herz spaces.
