Improving reliability allocation for complex networks using the Sea Lion Algorithm with three cost functions
(Işık University Press, 2026-04-01)This research addresses the issue of improving the reliability of complex networks under multiple cost constraints by employing the Sea Lion Optimization (SLO) algorithm. The problem is framed as a constrained optimization ... -
On Symmetric Neighbors degree sum exponent matrix
(Işık University Press, 2026-04-01)Recently, exponent matrices have emerged as a dynamic tool for studying networks by measuring node centrality. In this work, we define a Symmetric Neighbors degree sum exponent matrix SN E(G) of a graph G whose (i, j)th ... -
Eccentricity spectra of some graph operations in regular graphs
(Işık University Press, 2026-04-01)The eccentricity matrix of a graph G is derived from its distance matrix by letting the ijᵗʰ entry be equal to the distance between two vertices i and j, if the distance is the minimum of their eccentricities and zero ... -
Fixed point analysis in quasi-partial metric spaces using w−interpolative Hardy-Rogers type contractions
(Işık University Press, 2026-04-01)By using Interpolative Hardy-Rogers type contraction via w−admissibility approach in the framework of quasi-partial metric space, we introduce a new property that makes it convenient to investigate the existence and ... -
Uniqueness of certain fixed point theorems on multiplicative metric space with application
(Işık University Press, 2026-04-01)In this paper, we establish few fixed point results in multiplicative metric space and prove the existence of fixed points along with its uniqueness, by employing contraction mappings in complete multiplicative metric ... -
δβ-Open sets in Pythagorean fuzzy nano topological spaces
(Işık University Press, 2026-04-01)The purpose of this paper is to define and study a new class of sets called Pythagorean fuzzy nano δ (resp. δ pre, δ semi, δα and δβ)-open sets in Pythagorean fuzzy nano topological spaces. Analyse the basic properties of ... -
A study of fuzzy W-closed submodules and related concepts
(Işık University Press, 2026-04-01)In this paper we define fuzzy weak essential submodules to introduce the concept of fuzzy W-closed submodules of an R-module M. Further, we define fuzzy fully semiprime module. We use the condition of fuzzy fully semiprime ... -
Measuring jump sizes in asset prices with an indirect approach
(Işık University Press, 2026-04-01)The aim of this article is to estimate the magnitude of asset price jump sizes using an inverse method applied to historical financial data. Specifically, we adapt a particular form of the Merton jump-diffusion model for ... -
S₄ Separation and p-partition in all-path and detour convexities
(Işık University Press, 2026-04-01)In this work, we consider problems of S₄ and p-convex partition separations with respect to the all-path and the detour convexities. We give characterizations of p-all-path convex and p-detour convex graphs. With respect ... -
On strongly *-graphs and strongly multiplicative graphs
(Işık University Press, 2026-04-01)This paper studies strongly *-graphs as a variation of strongly multiplicative graphs. We show that every strongly multiplicative graph induces a strongly *-graph. We establish a relationship between the upper bounds on ...
