“…The solution methods of the Abel integral equations are collocation methods [9][10][11][12][13], Adomian decomposition methods [14][15][16], homotopy perturbation methods [17], quadrature methods [18][19][20], homotopy analysis methods [21], and Laplace transform methods [22][23][24][25][26]. Besides, Abel integral equations are also solved by using Chebyshev [27][28][29], Legendre [30,31], Taylor [32], Bernstein [33,34], Block-Pulse [35], and Laguerre [36] functions. Moreover, numerical methods on other fractional integral equations are hybrid collocation [37], smoothing technique [38], piecewise constant orthogonal functions approximation [39], the Haar wavelet method [40], the Galerkin method [41], Bernstein's approximation [42,43], the Simpson 3/8 rule method [44], mechanical quadrature [45], Legendre Pseudo spectral [46], and the iterative numerical method [47].…”
