Another combinatorial proof of a result of Zagier and Stanley
In this paper, we present another combinatorial proof for the result of Zagier and Stanley, that the number of n-cycles ω , for which ω(12 · · ·n) has exactly k cycles is 0, if n− k is odd and 2C(n+1,k) n(n+1) , otherwise, where C(n,k) is the unsigned Stirling number of the first kind. To this end, we generalize permutations to plane permutations and study exceedances via a natural transpositio...

To the best of our knowledge, there are no PDW models with a torso although there have been already many studies on PDW. This paper presents the first step towards applying the PDW principle to humanoid robots by adding a torso to a c...
