Abstract (EN):
Related to activities in matroids, J.E. Dawson introduced a construction that leads to partitions of the Boolean lattice of parts of a set into intervals. In this paper we characterize explicitly the partitions of a Boolean lattice into intervals that arise from this construction, and we prove that the construction is essentially unique.
