Upper bounds for covering total double Roman domination
(Işık University Press, 2023-07)Let G = (V, E) be a finite simple graph where V = V (G) and E = E(G). Suppose that G has no isolated vertex. A covering total double Roman dominating function (CT DRD function) f of G is a total double Roman dominating ... -
Using implicit relation to prove common coupled fixed point theorems for two hybrid pairs of mappings
(Işık University Press, 2016)Using implicit relation we establish two common coupled fixed point theorems under the conditions of weakly commutativity and w?compatibility on a complete metric space, which is not partially ordered. We do not use the ... -

Vertex coloring edge weightings of some square graphs
(Işık University Press, 2021)A k-edge-weighting w of a graph G is an assignment of integer weight, w(e) ? {1, 2, . . . , k}, to each edge e. A k-edge-weighting w induces a vertex coloring c by defining c(u) = P u?e w(e) for every u ? V (G), where u ? ... -
