On the r-dynamic coloring of the direct product of a path with either a complete graph or a wheel graph
(AIMS Press, 2021)
In this paper, it is explicitly determined the r-dynamic chromatic number of the direct product of any given path with either a complete graph or a wheel graph. Illustrative examples are shown for each one of the cases ...

On the r-dynamic coloring of some fan graph families
(Ovidius University Constanta, 2021)
In this paper, we determine the r-dynamic chromatic number of the fan graph Fm,n and determine sharp bounds of this graph invariant for four related families of graphs: The middle graph M(Fm,n), the total graph T(Fm,n), ...
