Perfect and multiple state transfer in oriented Cayley graphs
Ada Chan, Venkata Raghu Tej Pantangi, Andriaherimanana Sarobidy Razafimahatratra +1
We study perfect state transfer and multiple state transfer in oriented normal Cayley graphs. We construct examples in a variety of groups, ranging from abelian to nonsolvable, and…
Hilton-Milner Theorem for the -independent sets in a union of cliques
Karen Gunderson, Karen Meagher, Joy Morris +1
We give a Hilton-Milner Theorem for the -independent sets in the graph that is the union of copies of . That is, we determine the maximum intersecting families of -indep…
Intersecting Families of Spanning Trees
Peter Frankl, Glenn Hurlbert, Ferdinand Ihringer +4
A family of spanning trees of the complete graph on vertices is \emph{-intersecting} if any two members have a forest on edges in common. We prove an…
A new measure of robustness of ErdÅs--Ko--Rado Theorems on permutation groups
Karen Gunderson, Karen Meagher, Joy Morris +2
In this paper we introduce a new way of measuring the robustness of ErdÅs--Ko--Rado (EKR) Theorems on permutation groups. EKR-type results can be viewed as results about the indep…
Intersecting subsets in finite permutation groups
CaiHeng Li, Venkata Raghu Tej Pantangi, Shujiao Song +1
Let be transitive, and let be an intersecting subset, namely, the ratio of any elements fixes some point. An EKR-type problem…
