Near-factorizations in association schemes

Allen Herman, Alice Lacaze-Masmonteil, Karen Meagher +1

We formally initiate the study of -fold near-factorizations in association schemes. Namely, given an association , we consider the existence of a facto…

Cameron-Liebler sets in permutation groups

Jozefien D'haeseleer, Karen Meagher, Venkata Raghu Tej Pantangi

Consider a group acting on a set , the vector is a vector with the entries indexed by the elements of , and the -entry is 1 if maps to , and zero…

Induced forests in some distance-regular graphs

Karen Gunderson, Karen Meagher, Joy Morris +1

In this article, we study the order and structure of the largest induced forests in some families of graphs. First we prove a variation of the ratio bound that gives an upper bound…

On the intersection density of the Kneser Graph

Karen Meagher, Andriaherimanana Sarobidy Razafimahatratra

A set is \textsl{intersecting} if any two of its elements agree on some element of . Given a finite transitive permutation group $G\l…

Fusions of the generalized Hamming scheme on a strongly-regular graph

Allen Herman, Neha Joshi, Karen Meagher

In this paper we show that for any fusion of an association scheme , the generalized Hamming scheme is a nontrivial fusion of $H(n,\ma…

Erdős-Ko-Rado results for the general linear group, the special linear group and the affine general linear group

Karen Meagher, A. Sarobidy Razafimahatratra

In this paper, we show that both the general linear group $\gl{q}$ and the special linear group $\slg{q}$ have both the EKR property and the EKR-module property. This is done using…
