Generalized Hukuhara diamond-alpha derivative of fuzzy valued functions on time scales

Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics
In the literature, the delta and nabla derivatives have been considered separately in the study of fuzzy number valued functions on time scales. In this paper, to unify these two derivatives for fuzzy number valued functions, we propose a new dynamic derivative called the diamond-alpha derivative, defined via the generalized Hukuhara difference.

Finite-Difference Schemes for Interval Advection Equations Within a New Interval-Calculus Framework

Axioms
This paper focuses on three finite difference schemes for the interval advection equation based on a novel interval calculus framework. Different from classical interval arithmetic, this innovative framework equips the interval number space with a ...

An intuitionistic fuzzy differential equation approach for the lake water and sediment phosphorus model

Healthcare Analytics
Intuitionistic fuzzy sets cannot consider the degree of indeterminacy (i.e., the degree of hesitation). This study presents an intuitionistic fuzzy differential equation approach for the lake water and sediment phosphorus model.
