Multifractal analysis of weak Gibbs measures for non-uniformly expanding C^1 maps

We consider the local dimension spectrum of a weak Gibbs measure on a C^1 non-uniformly hyperbolic system of Manneville- Pomeau type. We present the spectrum in three ways: using invariant measures, uniformly hyperbolic ergodic measures and equilibrium states. We are also proving analyticity of the spectrum under additional assumptions. All three presentations are well known for smooth uniformly hyperbolic systems.
Comment: New version, main changes: the results hold for continuous potentials (previously: Holder potentials) and C^1 maps (previously: C^1+\alpha), we also prove analyticity of the spectrum
