Asymptotic formula for an expression in terms of the second kind of stirling numbers A good suggestion. In fact and for our actual applications, $m$ is usuallly fixed and usually less than $10$, and $r$ will vary near 1, often not more than $10$ and not less than $1/2$. Therefore we do want an approximate result for $\sum_{k=1}^m S(m,k)k!/r^{k-1}$. |

How many extreme maximal cliques are in an n*m 0-1 matrix? The major cardinality is not related to the minor cardinality. The major may be less than the minor, only dependent on the matrix and the conditions of extreme maximal biclique (1), (2) and (3). |

what is the sum of cardinalities of all elements of F at most? This solution is perfect. However, for s=1, the result reaches n*n somewhat bigger than expected. If we specify more conditions, the number may be reduced. Let's suppose that (1) each element of F is not a subnet of another one; and (2) cardinality of each element of F is not less than s. Then, whether or not the sum will become smaller? |
