Root square mean labeling of arrow graphs with encoding and decoding
(Işık University Press, 2025-06-01)A graph G with p vertices and q edges is called a Root Square mean labeling if it is possible to label the vertices x ∈ v with distinct labels ρ(x) from 1, 2, · · · , q + 1 in such a way that each edge e = ab is labeled ... -
Central star decomposition of complete graphs
(Işık University Press, 2025-06-01)In this paper, we define the central star decomposition of graphs and show that the oriented graphs correspond to central star decomposition of a simple graph and vice versa. -
Probabilistic insights into spatio-temporal garch model with location-dependent parameters

Existence of solution for impulsive fractional qr-difference equation of implicit form with nonlocal boundary condition
(Işık University Press, 2025-06-01)This study examines the conditions needed for the existence of solutions to an impulsive fractional qr-difference equation with the implicit form. The fractional derivative we analyze in the problem is of the Caputo type, ... -
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, ... -
