In this paper we explore topological factors in between the Kronecker factor and the
maximal equicontinuous factor of a system. For this purpose we introduce the concept of
sequence entropy -tuple for a measure and we show that the set of sequence entropy
tuples for a measure is contained in the set of topological sequence entropy tuples [H-
Y]. The reciprocal is not true. In addition, following topological ideas in [BHM], we
introduce a weak notion and a strong notion of complexity...
