A CHEBYSHEV SPECTRAL METHOD BASED ON OPERATIONAL MATRIX FOR LINEAR FUZZY FREDHOLMINTEGRAL EQUATION OF THE SECOND KIND

The main purpose of this work is to provide a numerical ap-proach for the fuzzy integral equations based on a spectral approach. AChebyshev polynomials is used to solve the fuzzy Fredholm integral equa-tions of the second kind via operational matrix. Numerical examples showthe errors decay exponentially provided that the kernel function and thesource function are su ciently smooth.
