Chebyshev-quasilinearization method for solving fractional singular nonlinear Lane-Emden equations

Authors: Amir Mohammadi ; Ghader Ahmadnezhad ; Nasser Aghazadeh ORCID-iD

    In this paper, we propose a method for solving some classes of the singular fractional nonlinear Lane-Emden type equations. The method is proposed by utilizing the second-kind Chebyshev wavelets in conjunction with the quasilinearization technique. The operational matrices for the second-kind Chebyshev wavelets are used. The method is tested on the fractional standard Lane-Emden equation, the fractional isothermal gas spheres equation, and some other examples. We compare the results produced by the present method with some well-known results to show the accuracy and efficiency of the method.
