A note on certain topological indices of the derived graphs of subdivision graphs
(Işık University Press, 2020)In this note, we correct some errors in S. M. Hosamani et al. [TWMS J. App. Eng. Math., 6(2), (2016) pp. 324–332]. The derived graph [G]† of a graph G is the graph having the same vertex set as G, with two vertices of ... -
Linear combinations of q-starlike functions of order alpha

Edge domination in some brick product graphs
(Işık University Press, 2020)Let G = (V, E) be a simple connected and undirected graph. A set F of edges in G is called an edge dominating set if every edge e in E ? F is adjacent to at least one edge in F. The edge domination number ?? (G) of G is ... -
Global attractor of the hyperbolic relaxation of the Swift-Hohenberg equation in R?
