In the study of the statistical properties of dynamical systems there are a number of important characteristics, e.g., entropy, Lyapunov exponents, etc. In this note we want to concentrate on the variance σ : C(M) → R of Hölder functions. The variance appears in statistical properties for both hyperbolic maps and flows. For a hyperbolic map T : M →M , a Hölder continuous function f : M → R and a Gibbs measure (for a Hölder continuous function g) we can define
