The functor “MEAS” and the classification of filtrations in measure spaces
Abstract: We will construct projective (and inductive) limits of iterations of spaces with measures and use these as
metric invariants of the filtrations. The classification of the filtrations and the corresponding combinatorics is
motivated by problems in ergodic theory, the theory of
random processes and group actions.
