Harmonic reciprocal status index and coindex of graphs
(Işık University Press, 2021)The reciprocal status of a vertex u is defined as the sum of reciprocal of the distances between u and all other vertices of a graph G. In this paper we have defined the harmonic reciprocal status index and coindex of a ... -
Fixed points in φ-ordered partial quasi-metric space
(Işık University Press, 2021)We obtain fixed points for an order preserving mapping in a preordered left p-complete partial quasi-metric space using a preorder induced by an appropriate function. In particular, we do not make use of any contraction condition. -
Fuzzy congruence on M??groups
(Işık University Press, 2021)In this paper, we consider an algebriac structure M?? group, which is a generalization of both the concepts module over a nearring and a gamma nearring, introduced by Satyanarayana [12]. In this paper, we define a fuzzy ... -
Certain types of graphs in interval-valued intuitionistic fuzzy setting

Minimal restrained monophonic sets in graphs
(Işık University Press, 2021)For a connected graph G = (V, E) of order at least two, a restrained monophonic set S of a graph G is a monophonic set such that either S = V or the subgraph induced by V ?S has no isolated vertices. The minimum cardinality ... -
