in this paper we develop B-spline collocation method for solving a class of self-adjoint singularly perturbed equations given by -epsilon(a(x)y')' + b(x)y(x) = g(x), a(x) greater than or equal to a* 0, a'(x) greater than or equal to 0, b(x) greater than or equal to b* > 0, y(0) = alpha, y(1) = beta We use the fitted mesh technique to generate piecewise uniform mesh, and use B-spline method which leads to a tridiagonal linear system. The convergence analysis is given and the method is shown to have uniform convergence of second order. Numerical illustrations are given in the end to demonstrate the efficiency of our method.
