Dynamics of Systems with a Discontinuous Hysteresis Operator and Interval Translation Maps
Axioms, 2021 We studied topological and metric properties of the so-called interval translation maps (ITMs). For these maps, we introduced the maximal invariant measure and study its properties. Further, we study how the invariant measures depend on the parameters of
