The vertex-isoperimetric number of the incidence andnon-incidence graphs of unitals

Alice M. W. Hui, Muhammad Adib Surani, Sanming Zhou

We derive upper and lower bounds for the vertex-isoperimetric number of the incidence graphs of unitals and determine its order of magnitude. In the case when a unital contains suf…

The isoperimetric number of the incidence graph of PG(n,q)

Andrew Elvey Price, Muhammad Adib Surani, Sanming Zhou

Let $Γ_{n, q}$ be the point-hyperplane incidence graph of the projective space $PG (n, q)$ , where $n \geq 2$ is an integer and $q$ a prime power. We determine the order…
