In this thesis, we are interested in characterizing typical (generic) dimensional properties of invariant measures associated with the full-shift system, T, in a product space whose alphabet is uncountable. More specifically, we show that the set of invariant measures with upper Hausdorff dimension equal to zero and lower packing dimension equal to infinity is a dense Gδ subset of M (T), the space of T-invariant measures endowed with the weak topology. We also show that the set of invariant measures with upper rate of recurrence equal to infinity and lower rate of recurrence equal to zero is a dense Gδ subset of M (T). Furthermore, we show that the set of invariant measures with upper quantitative waiting time indicator equal to infinity and lower quantitative waiting time indicator equal to zero is also residual in M (T). For topological dynamical systems with a dense set (in the weak topology) of periodic measures, we show that a typical invariant measure has, for each q > 0, zero lower q- generalized fractal dimension. This implies, in particular, that a typical invariant measure has zero upper Hausdorff dimension and zero lower rate of recurrence. Of special interest is the full-shift system (X, T) (where X = M Z is endowed with a sub-exponential metric and the alphabet M is a perfect and compact metric space), for which we show that a typical invariant measure has, for each q > 1, infinite upper q-correlation dimension. Under the same conditions, we show that a typical invariant measure has, for each s ∈ (0, 1) and each q > 1, zero lower s-generalized and infinite upper q-generalized dimensions. Finally, for measure preserving dynamical systems on metric spaces, we present sufficient conditions involving the upper and lower pointwise dimensions of the measure in order to obtain upper and lower bounds for its generalized fractal dimensions. We also obtain an extension of Young’s Theorem [59] involving the generalized fractal dimensions of the Bowen-Margulis measure of an Axiom A system. Furthermore, for Axiom A systems, we show that the set of invariant measures with zero correlation dimension, under a hyperbolic metric, is generic.
