Abstract: Numerical methods for bifurcation problems of the form

$\displaystyle Ly = \lambda f(y),\quad By = 0,$ ($ \ast$)

where $ f(0) = 0$ and $ f'(0) \ne 0$, are considered. Here y is a scalar function, $ \lambda $ is a real scalar, L is a linear differential operator and $ By = 0$ represents some linear homogeneous two-point boundary conditions. Under certain assumptions, it is shown that if $ (\ast)$ is replaced by an appropriate difference scheme, then there exists a unique branch of nontrivial solutions of the discrete problem in a neighborhood of a branch of nontrivial solutions of $ (\ast)$ bifurcating from the trivial solution and that the discrete branch converges to the continuous one. Error estimates are derived and an illustrative numerical example is included.
