Solution of Time Independent System of First Order Ordinary Differential Equations Using Embedding Method in Fuzzy Environment

UMYU Scientifica, 2023
In this study, time independent system of first order fuzzy ordinary differential equations is solved using embedding method. Results for the system of FODEs are obtained and a case of non-homogeneous system of FODEs is established and used to find the Eigen values in an  matrix with negative real numbers consisting of  fuzzy numbers.

New results for fractional ordinary differential equations in fuzzy metric space

AIMS Mathematics
<abstract><p>In this paper, we primarily focused on the existence and uniqueness of the initial value problem for fractional order fuzzy ordinary differential equations in a fuzzy metric space. First, definitions and relevant properties of the Gamma function and Beta function within a fuzzy metric space were provided.
