Abstract
In this paper we construct a family {T γ}, 0<γ<1/2, of exact endomorphisms of [0, 1] such that the invariant measurem γ ofT γ is equivalent to Lebesgue measure but has fractal correlation exponent ν=2γ. This shows that an almost complete dichotomy can exist between the information dimension and the correlation exponent in observable dynamical systems.
