    Natural and Cardinal splines collocation method for the resolution of Fredholm integral equation of the second kind
    (UNIVERSITE MOHAMED BOUDIAF - M’SILA- FACULTE MATHEMATIQUES ET DE L’INFORMATIQUE, 2019) Guettouche, Samah
    We have proposed two main methods, for approximating the solution of Fred￾holm linear integral equations of the second kind,based on cubic splines because of their simplicity,stabilityand their high order of convergence. In spite of its positive sounding name. the natural spline interpolation has little to recommend it from an approximation theoretic point of view. Due to its global character and the fact that the free-end conditions S 00 (a) = S 00 (b) = 0. produce an O (h 2 ) error.The natural spline interpolation method is complicated and requires many computations. How￾ever, the simulair results given for the method based on the cardinal spline are simple and more closer to the exacte solution. Also , we veriÖed that the presented method can be applied with large number of and remains stable.
