Cyclically t-complementary uniform hypergraphs
(European Journal of Combinatorics, 2010-05)
A cyclically t-complementary k-hypergraph is a k-uniform hypergraph with vertex set V and edge set E for which there exists a permutation 2 Sym.V/ such that the sets E; E ; E 2; : : : ; E t1 partition the set of all ...
Generating self-complementary uniform hypergraphs
(Discrete Mathematics, 2010-02)
In 2007, Szymanski and Wojda proved that for positive integers n; k with k less than n, a self-complementary k-uniform hypergraph of order n exists if and only if n/k is even. In this paper, we characterize the cycle type ...
