Symbolic differentiation algorithms for hyperbolic perturbation problems with Neumann conditions using asymptotic formulas and uniform difference schemes
(Işık University Press, 2026-09-01)In this paper, we investigate asymptotic formulas and ε-uniform difference schemes for the numerical solution of perturbation problems. Unfortunately, both of these numerical methods involving sine and cosine fitting ... -
A high-order Caputo-based numerical scheme for approximating the one-dimensional time-independent fractional Schrödinger equation
(Işık University Press, 2026-09-01)The time-independent fractional Schrödinger equation is pivotal for modeling quantum systems exhibiting nonlocal interactions and anomalous dispersion, for which analytical solutions are often intractable. This paper ... -
The Quantile Garch-Distributed Lag (QGDL) framework: a unified model for high-volatility time series
(Işık University Press, 2026-09-01)The essence of this article is that it has developed the Quantile GARCHDistributed Lag (QGDL) model as a recent and superior model to the QARDL model. Although the QARDL model is only able to deal with asymmetric relationships ... -
Ensitivity and optimizing dengue control in a two-time-delay transmission model
(Işık University Press, 2026-09-01)This study presents a detailed analysis of a dengue transmission model that incorporates two biologically motivated time delays, representing the intrinsic and extrinsic incubation periods in host-vector interactions. Based ... -
Isolate domination in the class of unicyclic graphs
(Işık University Press, 2026-09-01)A subset D of the vertex set V of a graph G is called a dominating set of G if every vertex in V − D is adjacent to a vertex in D. A dominating set D such that < D > has an isolated vertex is called an isolate dominating ... -
On a subclass of tilted starlike functions associated with epicycloid domain
(Işık University Press, 2026-09-01)This paper investigates a subclass of analytic and univalent functions defined on the open unit disk. A new subclass of tilted starlike functions associated with an epicycloid-shaped domain is defined. These functions are ... -
Properties and real data application of the Sine Alpha Power Burr XII regression model
(Işık University Press, 2026-09-01)We propose the Sine Alpha Power Burr XII (SAP Burr XII) distribution, obtained by applying the Sine Alpha Power transformation to the Burr XII distribution. and develop an accelerated failure time (AFT) regression model, ... -
Structural mathematics of dendrimers through complementary topological indices
(Işık University Press, 2026-09-01)Topological indices are key molecular descriptors in theoretical chemistry, nanotechnology and molecular modeling, linking structural and physicochemical properties. Recent advances in graph theory have broadened the ...
