International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.The bipolar fuzzy wave equation is crucial for modeling wave phenomena in systems characterized by dual uncertainty involving both positive and negative aspects of imprecise information. This study presents an innovative analytical framework for solving bipolar fuzzy wave equations using bipolar fuzzy Fourier sine transform under generalized Hukuhara ...

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.High‐order fractional fuzzy differential equations show great potential in modeling complex systems with memory effects and uncertainty. Existing qualitative theories seldom involve both Caputo‐type strongly generalized Hukuhara differentiability and coupled integral operators on infinite intervals. This paper presents a systematic investigation of the

Journal of Mathematics, Volume 2026, Issue 1, 2026.In this paper, a comprehensive study of the fuzzification and defuzzification of the Schrödinger equation in fuzzy neutrosophic environment is presented involving fuzzy truth (T) component, an indeterminacy (I) component, and a falsehood (F) component. Moreover, a modified numerical method of second‐order accuracy in both time and space based on Crank ...

Journal of Mathematics, Volume 2026, Issue 1, 2026.In this article, an in‐depth study of the advection–diffusion equation in a neutrosophic fuzzy environment is discussed for the first time in the literature, including truth (T), indeterminacy (I), and falsehood (F) fuzzy components. Furthermore, analytical and numerical methods that are Galilean transformation and explicit finite difference methods ...

Journal of Mathematics, Volume 2026, Issue 1, 2026.This paper introduces the concepts of approximate limit, approximate continuity, and approximate derivatives for fuzzy‐number‐valued functions and examines their fundamental properties. Also, the relationships between approximate limit, approximate derivative of fuzzy‐number‐valued functions, and their representations of λ‐level sets are investigated ...

Quasilinear approximation for interval-valued functions via generalized Hukuhara differentiability
, 2022 In this paper, a new generalized Hukuhara differentiability concept for interval-valued functions defined on Rn is proposed, which extends the classical Fréchet differentiability notion and provides an interval quasilinear approximation for an interval-
