Summary.
Let T : [0, 1] → [0, 1] be an expanding piecewise monotonic map. Conditions on T and \( {\rm inf}_{x\in [0,1]}|T^{\prime}x| \) implying the topological transitivity of T are investigated. For a monotonic mod one transformation T topological transitivity is obtained, if \( {\rm inf}_{x\in [0,1]}|T^{\prime}x| > 2 \). If T is a monotonic mod one transformation with three monotonic pieces, then \( {\rm inf}_{x\in [0,1]}|T^{\prime}x| \geq 2 \) implies the topological transitivity of T. An expanding monotonic mod one transformation T with lim x → 0+ T x = 0 or lim x → 1 - T x = 1 is topologically transitive.
