İdiz, F.Tanoǧlu, G.Aghazadeh, N.2024-05-052024-05-0520241017-1398https://doi.org/10.1007/s11075-023-01568-zIn this research, we study the numerical solution of fractional Lane-Emden type equations, which emerge mainly in astrophysics applications. We propose a numerical approach making use of Legendre wavelets and the quasilinearization technique. The nonlinear term in fractional Lane-Emden type equations is iteratively linearized using the quasilinearization technique. The linearized equations are then solved using the Legendre wavelet collocation method. The proposed method is quite effective to overcome the singularity in fractional Lane-Emden type equations. Convergence and error analysis of the proposed method are given. We solve some test problems to compare the effectiveness of the proposed method with some other numerical methods in the literature. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.eninfo:eu-repo/semantics/closedAccessFractional Differential EquationLane-Emden EquationLegendre WaveletQuasilinearizationArticle2-s2.0-8516183449110.1007/s11075-023-01568-z
