Runge-Kutta Nystrom method for solving fuzzy differential equations under generalized differentiability

K. Kanagarajan, R. Suresh


In this paper, we interpret a fuzzy differential equation by using the
strongly generalized differentiability concept. Utilizing the Generalized
Characterization Theorem, we investigate the problem of finding a nu-
merical approximation of solutions. The Runge-Kutta Nystrom approx-
imation method is implemented and its error analysis, which guarantees
pointwise convergence, is given. The method applicability is illustrated
by solving a linear first-order fuzzy differential equation.
