Abstract :
the concept of lucky k-polynomials and in particular lucky χ-polynomials was recently introduced. this paper introduces stirling number of the fourth kind and lucky partitions of a finite set in order to determine either the lucky k- or lucky χ-polynomial of a graph. the integer partitions influence stirling partitions of the second kind.
Keywords :
stirling number of the second kind , stirling number of the fourth kind , lucky partition , bell number
