AI总结:
本文在偶距离集合大小有界条件下,通过四个涉及连通度、阶和直径的条件,部分证明了猜想189,得出连通图可迹的充分条件。
AI中文摘要:
我们通过证明一个连通图 $G$ 满足 $\max\{\mathrm{dist_{even}}(v):v\in V(G)\}\le d_2+1$(其中 $\mathrm{dist_{even}}(v)$ 是与 $v$ 距离为偶数的顶点数,$d_2$ 是 $G$ 的第二小度)在四个条件中至少一个成立时是可迹的,从而在证明《写在墙上的II》中的猜想189方面取得了部分进展。这些条件涉及 $G$ 的顶点连通度、阶和直径。
英文摘要:
We make partial progress towards a proof of Conjecture 189 of Written on the Wall II by showing that a connected graph $G$ satisfying $\max\{\mathrm{dist_{even}}(v):v\in V(G)\}\le d_2+1$, where $\mathrm{dist_{even}}(v)$ is the number of vertices at an even distance from $v$ and $d_2$ is the second smallest degree of $G$, is traceable whenever at least one of four conditions holds. These conditions involve the vertex-connectivity, order, and diameter of $G$.
