Abstract
A random map is a discrete-time dynamical system in which one of a
number of transformations is randomly selected and applied at each
iteration of the process. In this paper, we study random maps. The
main result provides a necessary and sufficient condition for the
existence of absolutely continuous invariant measure for a random
map with constant probabilities and position-dependent probabilities.
