For subshifts of finite type, conformal repellers, and conformal horseshoes
, we prove that the set of points where the pointwise dimensions, local ent
ropies, Lyapunov exponents, and Birkhoff averages do not exist simultaneous
ly, carries full topological entropy and full Hausdorff dimension. This fol
lows from a much stronger statement formulated for a class of symbolic dyna
mical systems which includes subshifts with the specification property. Our
proofs strongly rely on the multifractal analysis of dynamical systems and
constitute a non-trivial mathematical application of this theory.
