Spectral radius of graphs with given size and odd girth

Zhenzhen Lou, Lu Lu, Xueyi Huang

Let $G (m, k)$ be the set of graphs with size $m$ and odd girth (the length of shortest odd cycle) $k$ . In this paper, we determine the graph maximizing the spectral radius…

Automorphism groups of a class of cubic Cayley graphs on symmetric groups

Xueyi Huang, Qiongxiang Huang, Lu Lu

Let $S_{n}$ denote the symmetric group of degree $n$ with $n \geq 3$ . Set $S = {c_{n} = (12 \dots n), c_{n}^{- 1}, (12)}$ . Let $Γ_{n} = Cay (S_{n}, S)$ be the Cayley graph on $S_{n}$ with…

The graphs with exactly two distance eigenvalues different from $- 1$ and $- 3$

Lu Lu, Qiongxiang Huang, Xueyi Huang

In this paper, we completely characterize the graphs with third largest distance eigenvalue at most $- 1$ and smallest distance eigenvalue at least $- 3$ . In particular, we determine…
