Abstract:
      Let $S$ be a closed orientable surface of genus $g\geq 2$, and $C(S)$ the curve complex of $S$. In the paper, we introduce the concepts of 2-path between edges in $C(S)$, which can be regarded as an analogue to the edge path between vertices in $C(S)$. We show that $C(S)$ is $2P$-connected, and the 2-diameter of $C(S)$ is infinite.
