Abstract: We elaborate thermodynamic and multifractal formalisms for
general classes of potential functions and their average
growth rates. We then apply these formalisms to certain
geometrically finite Kleinian groups which may have parabolic
elements of different ranks. We show that for these groups
our revised formalisms give access to a description of the
spectrum of `homological growth rates' in terms of Hausdorff
dimension. Furthermore, we derive necessary and sufficient
conditions for the existence of `strong phase transitions'.
