  In the context of 'infinite-volume mixing' we prove global-local mixing for
the Boole map, a.k.a. Boole transformation, which is the prototype of a
non-uniformly expanding map with two neutral fixed points. Global-local mixing
amounts to the decorrelation of all pairs of global and local observables. In
terms of the equilibrium properties of the system it means that the evolution
of every absolutely continuous probability measure converges, in a certain
precise sense, to an averaging functional over the entire space.
