Webb16 apr. 2024 · An injective k-edge-coloring of a graph G is an assignment of colors, i.e. integers in {1, … , k}, to the edges of G such that any two edges each incident with one distinct endpoint of a third edge, receive distinct colors. The problem of determining whether such a k-coloring exists is called k-INJECTIVE EDGE-COLORING. east tropicana animal hospital
