As future researches, we can use finite and divided differences methods, fuzzy spline interpolation, and fuzzy quasi-interpolation for solving two-dimensional linear or nonlinear fuzzy Fredholm integral equations
These equations are considered the Fredholm integral equations
of the first kind with respect to the normal derivative qi on the interface [psi].sub.1] and to the normal derivative [[??].sub.3] on the interface [psi].sub.2], respectively.
