We investigate mixed partitions with extra condition on the sizes of the blocks. We give a general formula and the generating function. We consider in more details a special case, determining the generating functions, some ...

We study set partitions with r distinguished elements and block sizes found in an arbitrary index set S . The enumeration of these ( S, r )-partitions leads to the introduc- tion of ( S, r )-Stirling numbers, an extremely ...

In the paper, the authors present several new relations and applications for the combinatorialsequence that counts the possible partitions of a finite set with the restriction that the size ofeach block is contained in a ...
