Permutations Statistics of Indexed and Poset Permutations by Einar Steingrimsson
The definitions of descents and excedances in the elements of the symmetric group Sd are generalized in two different directions. First, descents and excedances are defined for indexed permutations, i.e. the elements of the group Sd = Zn I Sd, where is wreath product with respect to the usual action of Sd by permutation of [d]. It is shown, bijectively, that excedances and descents are equidist...
متن کاملSome Heuristics for the 2-Poset Cover Problem
Posets are abstract models that may be considered as generating a set of linear orders, which are permutations on some base set. The problem of determining a minimum set of posets that can exactly generate a specified input set of linear orders is referred to as the Poset Cover Problem, and this problem is NP-Hard in the general case. In this study, we investigate a constrained version of the p...

This situation turns the question of the necessity for academic criticism of the data which entered the of cial departmental statistics of the MVD, Ministry of Justice and Procura...
متن کاملWavelets in Statistics : Some Recent
Wavelet methods in statistics are in their infancy as far as the range of problems to which they have been applied is concerned. Some elementary aspects of wavelets are reviewed, concentrating on the discrete wavelet transform, because of its relevance to practical and computational statisticians. Several recent areas of research are discussed, concentrating on extensions of the standard paradi...
