Abstract: | Summary In this paper, we continue the study undertaken in our earlier paper M1]. One of the main results here can be described as follows. LetX
0,X
1, ... be a sequence of iid random affine maps from (R
+)
d
into itself. Let us write:W
n
X
n
X
n
–1...X
0 andZ
n
X
0
X
1...X
n
, where composition of maps is the rule of multiplication. By the attractorA(u),u(R
+)
d
, we mean the setA
u={y(R+)d:P(Wn
uN i.o.) > 0 for every openN containingy}. It is shown that the attractorA(u), under mild conditions, is the support of a stationary probability measure, when the random walk (Z
n
) has at least one recurrent state. |
