Properly colored even cycles in edge-colored complete balanced bipartite graphs

Shanshan Guo, Fei Huang, Jinjiang Yuan +2

Consider a complete balanced bipartite graph $K_{n,n}$ and let $K_{n,n}^c$ be an edge-colored version of $K_{n,n}$ that is obtained from $K_{n,n}$ by having each edge assigned a ce…
