Incorporating the influence of hunting cooperation and competition into the prey-predator model
(Işık University Press, 2026-05-01)This mathematical model consists of three nonlinear ordinary differential equations between two prey (N1, N2) and only one predator (P). The two prey (N1, N2) grow logistically under predator pressure, and the predator ... -
Higher-order accurate compact schemes and analysis for the time-fractional Black-Scholes model
(Işık University Press, 2026-05-01)This work is focused on the construction of numerical schemes with higherorder accuracy in space and time to solve the time-fractional Black-Scholes model that governs the price of European options. We develop three numerical ... -
A characterization of E-completeness in vector metric spaces with an application in fixed point theory
(Işık University Press, 2026-05-01)The main purpose of this article is to introduce the notion of dᵥ-point in a vector metric space which is a generalization of the notion of d-point in metric spaces and extend Weston’s characterization of metric completeness ... -
Some properties of fuzzy disjointness in fuzzy lattices
(Işık University Press, 2026-05-01)In this paper, we introduce the concept of fuzzy general disjointness property along with its notation. Our results indicate that a fuzzy section semi-complemented lattice possesses the fuzzy atomic covering property if ... -
Path center of a fuzzy graph based on µ-distance
(Işık University Press, 2026-05-01)Graph theory has put forward a mathematical foundation for modelling and fine tuning communication and transportation networks. Centers and path centers serve as effective tools for optimizing traffic flow and efficiently ... -
Hybrid bi-ideals and hybrid quasi-ideals in ordered semirings
(Işık University Press, 2026-05-01)Fuzzy set theory has been proven to be a powerful tool for dealing with uncertainty in decision-making processes. This theory addresses uncertain parameters. Soft set theory is another mathematical concept used for managing ... -
On a distinct family of iterative schemes for weak contractions
(Işık University Press, 2026-05-01)This article introduces a distinct collection of fixed point iteration schemes. For this collection, a strong convergence result is established involving weak contractions. Additionally, a comparison result is obtained to ... -
Generalized solutions for time ψ-fractional wave equation
(Işık University Press, 2026-05-01)This paper focuses on the fractional wave problem with the use of a new fractional derivative in Colombeau algebra. Using Banach’s fixed point theorem and Laplace transforms, we give and prove the integral solution of the ... -
Adjusted explained variation measure for zero-inflated poisson regression model
(Işık University Press, 2026-05-01)Explained variation measures are very popular in regression models. They explain the amount of variation in the dependent variable by the explanatory variables. In some situations, a small sample size is available in ... -
Slavoj Žižek. Looking Awry: An Introduction to Jacques Lacan through Popular Culture
(Işık Üniversitesi Yayınları, 2026-04-29)This book review examines Looking Awry by Slavoj Žižek as a key text that bridges ideology critique, psychoanalysis, and popular culture. Drawing on the theoretical framework of Jacques Lacan, the review highlights how ... -
The evolution of leadership theories and the role of transformational leadership in modern organizations
(Işık Üniversitesi Yayınları, 2026-04-29)This review paper examines recent studies on the evolution of leadership theories and highlights the importance of transformational leadership in modern organizations operating in volatile, uncertain, complex, and ambiguous ... -
The role of inner speech in modulating electrophysiological stress responses
(Işık Üniversitesi Yayınları, 2026-04-29)The frequency and reliance on inner speech (IS) vary across individuals and may influence selfregulation processes such as emotion regulation and impulse control. This study examined whether IS frequency is associated with ... -
Does supply chain integration enhance humanitarian supply chain performance? an empirical investigation of operational outcomes
(Işık Üniversitesi Yayınları, 2026-04-29)Humanitarian supply chains (HSC) operate in high-uncertainty environments where speed and adaptability are critical, yet existing supply chain integration (SCI) models are primarily derived from commercial contexts. This ... -
Foreign policy as performance: contesting Europe in Turkey’s 2017 referendum
(Işık Üniversitesi Yayınları, 2026-04-29)In what ways does foreign policy contestation contribute to regime consolidation under populist rule? Using Turkey's 2017 constitutional referendum as a case study, this article examines how the Justice and Development ... -
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 ... -
