The A-partition function pA(n) enumerates all A-partitions of n. In particular, we have that pA(n)=0 whenever n is a negative integer and pA(0)=1 with the empty partition λ=(). The generating function for pA(n) is given by ∑n=0∞pA(n)xn=∏a∈A11−xa. For example, if...
3. The set of Gödel numbers of atomic formulas is representable. PROOF. a is the Gödel number of an atomic formula iff (∃i < aa lh a, ∃k < a) [i is a sequence number & (∀j < lh i)(i)j is the Gödel number of a term & k is the value of h at some (lh...
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...

To solve the problem, we need to find the number of elements in the union of sets A and B, given that
ways, leaving us with n-3 elements. To ensure that the gaps between the first and second and the second and third elements are not empty, we need to partition the set {4,...,n} into subsets of size 4, 3, and 2. The number of such partitions is...

If the two cells lie in the same row, the contraction is nontrivial. Hence, all rows must have even lengths so that the resulting empty diagram correspond to a nontrivial scalar. However, the equality of the dimensions does not imply a simple bijective correspondence between the even row ...

If A is not simply connected, then the connected components (that is, open and closed subsets) of its complement C¯ not containing the point ∞ are the “holes” of A. A region is a nonempty open set of C. A domain is a non-empty connected open set of C. When r > 0, the ...
