comment Central Limit Theorem(s) for irrational rotation
@Christian: CLT does hold for dynamical systems which are sufficiently ergodic (e.g. hyperbolic actions on a torus). So independence is far from necessary for CLT to hold.

@DouglasZare: edited so it's clear the relevant r.v. have mean zero.

comment Gini Coefficient and Renyi Entropy
Something is off with your lower bound on G({p_i}). G({0,...,0,1}) is equal to 1-1/n, but H_0({0,...,0,1})=0, so your bound would give G \geq 1. Is the factor "-1" in the definition of G correct?

comment Speed on recurrent graphs
@DelioM. : we start a random walk at point X_0 and look at the expected distance from X_0 after t steps (this might a priori depend on the choice of X_0).
