“…To estimate the error and compute the rate of convergence in the computed numerical solution, the double mesh principle was used [18,21,24]. As the exact solution of the problem was unknown, and therefore to approximate the pointwise errors |(˜ − )(η i )|; i = 0, 1, 2, .…”

“…Motivated by the works of Leung [2], Jian-ping and Zong-chi [4], Mo and Wen [9] and Natesan et al [15], we consider the following boundary value problem for singularly perturbed third order differential equation with a turning point at x = 0:…”

“…In [11] Kadalbajoo and Patidar applied a numerical method based on cubic spline with nonuniform grid for a second order SPTPP. Natesan et al [15] proposed a parameter uniform numerical method in which piecewise-uniform mesh is combined with classical finite difference scheme to obtain the numerical solution. For more detail one may refer [18] and the references therein.…”

“…Such behavior results in some major computational difficulties in the numerical treatment of singularly perturbed problems. Standard finite difference or finite element methods used on uniform meshes can not obtain accurate approximate solutions and in recent years a large number of special-purpose methods have been proposed [1][2][3][4][5][6][7].…”

“…To the best of our knowledge, there are only a few results concerning numerical solutions of singularly perturbed turning point problems. Natesan et al [1] proposed a parameter uniform numerical method for singularly perturbed turning point problems exhibiting boundary layers. Kadalbajoo et al [2] solved stiff singularly perturbed turning point problem having twin boundary layers by a collocation method.…”
