Báo cáo toán học: "A finite word poset" pot

... 2000 Abstract Our word posets have finite words of bounded length as their elements, with the words composed from a finite alphabet. Their partial ordering follows from the inclusion of a word as a subsequence ... mentioned, combinatorics on words has been almost exclusively concerned with the infinite poset P (∞) , comprising all finite sequences. There are very few results about...

If the group acts on a finite interval, then of course the number of inversions is finite. If it ac...

In data-centric storage, the home nodes can be hot spots, and the hot spot traffic cost can be written as follows [30]: EH GHT = R [ n¯e s p d + 1 γ m¯q s p q ] ... high, congestion may happen around the center of the network and creates a hot spot region problem. A solution to hot spot region problem is to adjust the size of the central region (i.e., number...
