Abstract
The r-Bell number B^r(G) of a simple labeled graph G is the number of partitions of its vertex set whose blocks are independent sets of G where the first r-vertices are in different blocks. The number of these partitions with k blocks is the (graphical) r- Stirling number S^r(G; k) of G. On this particular paper we will investigate the integer sequence of r-Bell numbers for different kinds of graphs.
