HIGHLIGHTS
- who: Erdou030bs-Ko-Rado Theorem. et al. from the Department of, Faculty of Science, King Mongkut`s University of Technology Thonburi, Bangkok, Thailand have published the research: On disjoint cross intersecting families of permutations, in the Journal: (JOURNAL)
- how: The following definition was introduced by Borg in his paper too.
SUMMARY
For a permutation σ ∈ Pr,n, the authors set σ(i)=xi if (i, xi ) ∈ σ. A subfamily A of Pr,n is intersecting if A ∩ B 6=∅ for all A, B ∈ A. For k ≥ 2, subfamilies A1, A2,.., Ak of Pr,n . . .
