    On irregular coloring of wheel related graphs
    (Ankara Üniversitesi Fen Fakültesi, 2019-08-01) Rohini, A.; Venkatachalam, M.; Other; Other
    An irregular coloring is a proper coloring in which distinct vertices have different color codes. In this paper, we obtain the irregular chromatic number for middle graph, total graph, central graph and line graph of wheel graph, helm graph, gear graph and closed helm graph.

    On irregular colorings of double wheel graph families
    (Ankara Üniversitesi Fen Fakültesi, 2019-02-01) Rohini, A.; Venkatachalam, M.; Other; Other
    An assignment of colors to the vertices of a graph, so that no two adjacent vertices get the same color is called a proper coloring. An irregular coloring of a graph is a proper vertex coloring that distinguishes vertices in the graph either by their own colors or by the colors of their neighbours. In this paper, we investigate the irregular chromatic number for the middle graph, total graph, central graph and line graph of double wheel graph.
