G. Krupa, ERGODIC-THEOREMS FOR SUBADDITIVE SUPERSTATIONARY FAMILIES OF RANDOM SETS WITH VALUES IN BANACH-SPACES, Studia Mathematica, 131(3), 1998, pp. 289-302
Under different compactness assumptions pointwise and mean ergodic the
orems for subadditive superstationary families of random sets whose va
lues are weakly (or strongly) compact convex subsets of a separable Ba
nach space are presented. The results generalize those of [14], where
random sets in R-d are considered. Techniques used here are inspired b
y [3].
