Diameter of Ramanujan Graphs and Random Cayley Graphs

Naser T Sardari

We study the diameter of LPS Ramanujan graphs $X_{p, q}$ . We show that the diameter of the bipartite Ramanujan graphs is greater than $(4/3) lo g_{p} (n) + O (1)$ where $n$ is the numb…

Optimal strong approximation for quadratic forms

Naser T Sardari

For a non-degenerate integral quadratic form $F (x_{1}, \dots, x_{d})$ in $d \geq 5$ variables, we prove an optimal strong approximation theorem. Let $Ω$ be a fixed compact subset of the…
