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 ... -
