The number of subsets of {(a),(b,c),d,e) is 00:51 If R={(a,a),(a,c),(b,c),(b,b),(c,c),(a,b)} on the set X=(a,b,c), then ... 02:28 The relation R={(2,3),(1,1),(1,3),(3,1)} on the set A=(1,2,3) is 01:48 Which of the following statemen...
Summary: Let $S$ be a finite set that consists of $n$ different elements and $k\\geq 2$ be a natural number. A family $\\Cal F$ of subsets $S_1,\\dots,S_r$, $r\\geq k$, of the set $S$ is called $k$-undivided if the intersection of any $k$ sets of $\\Cal F$ ...
Find the number of subsets for the set. M = {x | x is an integer between 1 and 8} Set M has--- ?subsets. Subset: If there are two sets A and B then A is known as the subset of the B if all the elements of A are in B and B is said to...
Cardinality:The cardinality of the empty set is zero. The cardinality of an infinite set is infinite. Two sets have the same cardinality if there is a one-to-one mapping between their elements. Euler Diagram:An Euler diagram represents sets as regions enclosed by circles. If A is a subset...
A natural example of such a function is the A-partition function pA(n), which enumerates the number of partitions of n with parts in the fixed finite multiset A={a1,a2,…,ak} of positive integers. For an arbitrary positive integer d, we present efficient criteria for both the order d...

A hypergraph is a pair H=(V,E), where V is an n element set of vertices of H and E is a family of m non-empty subsets of V called edges or hyperedges. Let [k] denote the set of integers {1,…,k}. A k-coloring of hyperedges of H=(V,E) is a mapping c:E→[k] such...
