All $3$ -transitive groups satisfy the strict-EKR property

Venkata Raghu Tej Pantangi

A subset $S$ of a transitive permutation group $G \leq Sym (n)$ is said to be an intersecting set if, for every $g_{1}, g_{2} \in S$ , there is an $i \in [n]$ such that $g_{1}…

Cameron-Liebler sets in permutation groups

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

Consider a group $G$ acting on a set $Ω$ , the vector $v_{a, b}$ is a vector with the entries indexed by the elements of $G$ , and the $g$ -entry is 1 if $g$ maps $a$ to $b$ , 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…
