“…The dynamics of "Lorenz" plateau maps will decompose in three blocks: (1) the set Λ of points whose orbits avoid the critical region C(f t ) := [c 0 , c 1 ], (2) the set of points thats eventually go into the left side of the critical region and follow this critical value, i.e., Γ 0 := {x ; O + ft (x) ∩ [c 0 , c)} and (3) the points that visit the right side and follow its critical value, that is, Γ 1 := {x ; O + ft (x) ∩ (c, c 1 ]}. By Mañe, Leb(Λ) = 0.…”
