Hypergraph isomorphism
A hypergraph homomorphism is a map from the vertex set of one hypergraph to another such that each edge maps to one other edge. A hypergraph is isomorphic to a hypergraph , written as if there exists a bijection and a permutation of such that The bijection is then called the isomorphism of the graphs. Note that Webrigidity in Rd is not a generic property of a (d+ 1)-uniform hypergraph. 1 Introduction For any natural number d, a (d + 1) ... The space V(d,R) is an algebraic group, isomorphic to the semidirect product SL(d,R) ⋉ Rd, the factors of which are themselves algebraic groups of dimensions d2 −1 and d respectively. Hence dim(V(d,R)) = (d2 −1)+d.

WebA poset P is in the class Q (resp. Q 0) if it has no induced subposet isomorphic to P 1, P 2, P 3 (resp. P 1, P 2, P 3, P 4) of Figure 2 and their duals, where P 3 has n vertices, n 6. Obviously the class Q 0 is included in Q . We prove that if P is in Q , then H (P ) has the dual K onig property.

Some motivation for this definition comes from the following facts about regular hypergraphs. The diameter of a hypergraph is just the maximum of the minimum of all lengths of paths between any two vertices.
