Abstract: For a simple connected graph G = (V (G),E(G)) and a positive integer k, a radio k-labelling of G is a mapping $f \colon V(G)\rightarrow \{0,1,2,\ldots \}$ such that $|f(u)-f(v)|\geqslant k+1-d(u,v)$ for each pair of… read more here.

Abstract: Radio k-coloring of a graph G is an assignment f of positive integers (colors) to the vertices of G such that for any two distinct vertices u and v of G, the difference between their… read more here.
