## Abstract For blockโpartitioned matrices of the __GI/M/__1 type, it has been shown by M. F. Neuts that the stationary probability vector, when it exists, has a matrixโgeometric form. We present here a new proof, which we believe to be the simplest available today.
## Abstract This is a contribution to the study of the Muchnik and Medvedev lattices of nonโempty ฮ ^0^~1~ subsets of 2^__ฯ__^. In both these lattices, any nonโminimum element can be split, i. e. it is the nonโtrivial join of two other elements. In fact, in the Medvedev case, if__P__ > ~M~ __Q__, th
