Properly colored cycles in edge-colored complete graphs containing no monochromatic triangles: a vertex-pancyclic analogous result

Ruonan Li

A properly colored cycle (path) in an edge-colored graph is a cycle (path) with consecutive edges assigned distinct colors. A monochromatic triangle is a cycle of length $3$ with t…

Rainbow triangles in arc-colored digraphs

Wei Li, Shenggui Zhang, Ruonan Li

Let $D$ be an arc-colored digraph. The arc number $a (D)$ of $D$ is defined as the number of arcs of $D$ . The color number $c (D)$ of $D$ is defined as the number of colors assigned…

Rainbow triangles in arc-colored tournaments

Wei Li, Shenggui Zhang, Yandong Bai +1

Let $T_{n}$ be an arc-colored tournament of order $n$ . The maximum monochromatic indegree $Δ^{- m o n} (T_{n})$ (resp. outdegree $Δ^{+ m o n} (T_{n})$ ) of $T_{n}$ is the maximum number of…

Vertex-disjoint properly edge-colored cycles in edge-colored complete graphs

Ruonan Li, Hajo Broersma, Shenggui Zhang

It is conjectured that every edge-colored complete graph $G$ on $n$ vertices satisfying $Δ^{m o n} (G) \leq n - 3 k + 1$ contains $k$ vertex-disjoint properly edge-colored cycles. We confir…
