A New Feasibility Condition for the AT4 Family

Zheng-Jiang Xia, Jae-Ho Lee, Jack H. Koolen

Let $Γ$ be an antipodal distance-regular graph with diameter $4$ and eigenvalues $θ_{0} > θ_{1} > θ_{2} > θ_{3} > θ_{4}$ . Then $Γ$ is tight in the sense of Jurišić, Koolen, and Terwilliger [12] when…

Sufficient conditions for graphs to be $k$ -connected, maximally connected and super-connected

Zhen-Mu Hong, Zheng-Jiang Xia, Fuyuan Chen +1

Let $G$ be a connected graph with minimum degree $δ (G)$ and vertex-connectivity $κ (G)$ . The graph $G$ is $k$ -connected if $κ (G) \geq k$ , maximally connected if $κ (G) = δ (G)$ , and su…

Pebbling on Jahangir graphs

Zheng-Jiang Xia, Zhen-Mu Hong, Fu-Yuan Chen

The pebbling number of a graph $G$ , $f (G)$ , is the least $p$ such that, however $p$ pebbles are placed on the vertices of $G$ , we can move a pebble to any vertex by a sequence of m…

A method to determine algebraically integral Cayley digraphs on finite Abelian group

Fei Li

Researchers in the past have studied eigenvalues of Cayley digraphs or graphs. We are interested in characterizing Cayley digraphs on a finite Abelian group G whose eigenvalues are…
