Concentration inequalities are a powerful tool to estimate the fluctuations of observables more general than ergodic sums: one can consider any observable $F(x,\ldots,T^n x)$ provided it is separately Lipschitz. Such inequalities can be established for non-uniformly hyperbolic systems and we shall present some applications.
