Regularized gap functions for p-strongly monotone variational-hemivariational inequalities and applications to global error bounds
(Işık University Press, 2025-06-01)The paper studies regularized gap functions for a general class of elliptic variational–hemivariational inequalities by employing the sum rule of Clarke’s generalized directional derivatives. We first devote regularized ... -
Coincidence points in b-metric spaces via l-simulation functions and digraphs
(Işık University Press, 2025-06-01)The study of fixed point theory combining digraphs and L-simulation functions is a new development in the domain of contractive type single valued theory. In this paper, we introduce the notion of a generalized LG- contraction ... -
A study on maximum cardinality r-L(2, 1)-labelling problem on circular-arc graph and its application
(Işık University Press, 2025-06-01)Graph labelling is one of the most applicable problem in graph theory, often applied to solve real-world challenges. This article explores a range of L(2, 1)-labelling problems (L21LPs), specifically focusing on the r-L21LP ... -
On Italian domination number of unary operations of special graphs
(Işık University Press, 2025-06-01)For a graph G = (V, E), an Italian dominating function (IDF) f : V → {0, 1, 2} has the property that for every vertex v ∈ V with f(v) = 0, either v is adjacent to a vertex assigned 2 under f, or v is adjacent to at least ... -
Completeness and compactness in type-2 fuzzy metric spaces
(Işık University Press, 2025-06-01)In this paper completeness and compactness in type-2 fuzzy metric spaces are studied. Cantor’s intersection theorem characterizing the completeness of a type-2 fuzzy metric space is proved. Baire’s category theorem is also ... -
Claw-decomposition of the Kneser graph KGn,3
(Işık University Press, 2025-06-01)The Kneser graph KGn,3 is the graph whose vertices are the 3-element subsets of n-elements, in which two vertices are adjacent if and only if their intersection is empty. A claw is a star with three edges. In this paper, ... -
An efficient solution for interval valued Trapezoidal Fuzzy Bounded Variable Problem and its real life application
(Işık University Press, 2025-06-01)In this research examined a completely fuzzy Interval valued Trapezoidal Bounded Variable Linear Programming Problem (FFIVBVLPP) where all the parameters of objective functions, and resource vector decision variables are ... -
Mathematical model on Covid-19 transmission with absence and presence of second dose of vaccination in Turkey
(Işık University Press, 2025-06-01)In this paper, we have explored COVID-19 transmission dynamics with vaccination drive in Turkey. The present study elaborates the impact of vaccination drives to prevent infection transmission among Turkish people. The ... -
Sombor index of fuzzy graph
(Işık University Press, 2025-06-01)Topological indices (TI) play a crucial role across various research domains, including network theory, spectral graph theory, and molecular chemistry. These indices are created primarily in the context of crisp graphs, ... -

Picture fuzzy ideals in near rings under group actions
(Işık University Press, 2025-05-01)A useful technique for examining the symmetry and automorphism characteristics of near rings is group action. In this paper, we study picture fuzzy (PF) ideals of near rings, which are extension of both fuzzy and intuitionistic ... -
Some fixed point theorems in dislocated quasi extended b-metric space
(Işık University Press, 2025-05-01)In 2017, Kamran et al. [14] introduced the notion of extended b-metric space as a generalization of b-metric space. The concept of dislocated quasi extended b-metric space was presented by Nurwahyu [15]. In this paper, ... -
Development and analysis of new nonparametric techniques for causal inference in observational studies
(Işık University Press, 2025-05-01)The lack of randomization methods in observational studies blocks researchers from reaching valid conclusions based on their data. The lack of randomisation techniques results in multiple experimental factors which appear ... -
On the traversability of new composition of total graphs
(Işık University Press, 2025-05-01)The F-composition F(G)[H] is a graph with the set of vertices V (F(G)[H]) = (V (G) ∪ E(G)) × V (H) and two vertices u = (u1, u2) and v = (v1, v2) of F(G)[H] are adjacent if and only if [u1 = v1 ∈ V (G) and (u2, v2) ∈ E(H)] ... -
