We give a sufficient condition for the construction of Markov fibred systems using countable Markov partitions with locally bounded distortion. 0. Introduction. Let X be a compact metric space with metric d and T : X → X be a noninvertible piecewise C-invertible map, i.e. there exists a finite or countable partition X = ⋃ i∈I Xi such that ⋃ i∈I intXi is dense in X and (1) For each i ∈ I with intXi 6= ∅, T |intXi : intXi → T (intXi) is a homeomorphism and (T |intXi) −1 extends to a homeomorphism vi on cl(T (intXi)). (2) T ( ⋃ intXi=∅ Xi) ⊂ ⋃ intXi=∅ Xi. (3) {Xi}i∈I generates F with respect to T , where F is the σ-algebra of Borel subsets of X. We set A = cl(intA) (A ⊂ X) and define α = {Xi}i∈I . Then α is a finite or countable partition of a dense subset of X which is not necessarily a disjoint family. We impose the Markov property on α: (4) int(Xi ∩ TXj) 6= ∅ implies TXj ⊃ Xi. Let A denote the set of all admissible sequences with respect to (T, α), i.e. ∀i = (i1 . . . in) ∈ A, int(vi1◦. . .◦vin(TXin)) 6= ∅. We write vi1◦. . .◦vin = vi1...in and vi1 ◦ . . . ◦ vin(TXin) = X i for i ∈ A. Finally we let |i| = n. A measure m on X is called locally nonsingular if it is nonsingular with respect to the maps v i : Xi → TXi for each Xi ∈ α and if the boundary of α has measure 0. If m is finite, the system (X,F , T,m, α) is called a Markov map (Markov fibred system) (cf. [2] or [4]). There are some canonical examples for this notion: Markov shifts and maps of the interval (e.g. 2000Mathematics Subject Classification: 37A40, 28D99, 37A30, 37C30, 37D35, 37F10, 37A45.
