Uranium, Mining and HydrogeologyThis paper is concerned in a class of bifurcation problems in ordinary differential equations. It is shown how some basic aspects of bifurcation can be handled by standard methods of numerical analysis. The procedure is illustrated by four examples.

Furthermore, under analogous assumptions a local convergence theorem holds in the nonlinear case. In this paper we give two global versions of this local result, one which yields a global stabi
