A classification of mahonian maj-inv statistics

Finally, in Section 4, we prove that the set of subexcedent words in S n , n is related to ternary trees and Dumont permutations of the second kind [12] avoiding the classical

In the present paper we derive a general equidistribution property on Euler-Mahonian set-valued statistics on permutations, which unifies the above four refinements.. We also state

As for the symmetric group of ordinary permutations there is also a statistical study of the group of signed permutations, that consists of calculating multi- variable

Towards ameliorating this we in- troduce the BLIINDS index (BLind Image Integrity Notator using DCT Statistics) which is a no-reference approach to image quality assessment that

Indeed, [4] proved Theorem 1.10 using standard rim hook tableaux instead of character evaluations, though virtually every application of their result uses the
