arXiv:1406.7317 · doi:10.1155/2014/870596
Abstract
Since 1950s, mathematicians have successfully interpreted the traditional Eulerian numbers and Eulerian numbers combinatorially. In this paper, the authors give a combinatorial interpretation to the general Eulerian numbers defined on general arithmetic progressions { a, a+d, a+2d,...}.
