Essential edges of Poisson random hypergraphs, Random Structures & Algorithms Consider a random hypergraph on a set of N vertices in which, for 1 ≤ k ≤ N, a Poisson(Nβk) number of hyperedges is scattered randomly over all subsets of size k. We collapse the hypergraph by running the ...

A toll interval between u,v∈V(G), T(u,v), is the set of all vertices of G that lie in some tolled u,v-walk. A set S⊆V(G) is t-convex if T(u,v)⊆S for any u,v∈S. The size of a maximum proper t-convex set S⊆V(G) is called the t-convexity number of a...
The Stirling numbers of the second kind, or Stirling partition numbers, describe the number of ways a set with n elements can be partitioned into k disjoint, non-empty subsets. Common notations are S (n, k) and,-. The study is finalized with an extraordinary identity between the second ...
Tversky (1972b) stated that the number of free parameters in the Elimination-By-Aspects (EBA) model is ~(2m) - 3 (the number of proper nonempty subsets of the full choice set [T], minus an arbitrary unit of measurement), where m is the number of objects in the total set of ...

On the covering number of small symmetric groups and some sporadic simple groups A set of proper subgroups is a cover for a group if its union is the whole group. The minimal number of subgroups needed to cover G is called the covering ... NP Swartz - 《Groups Complexity Cryptology》 被...
The following conjecture of Katona is proved. Let X be a finite set of cardinality n, 1 m 2 n. Then there is a family F, | F| = m, such that F ∈ F, G X, | G | > | F | implies G ∈ F and F minimizes the number of pairs ( F 1, F 2), F 1, F 2 ∈ F F ...
