A nonlinear eigenvalue problem \(u=TG(\lambda,u)\) is approximated by a family \(u_ h=T_ hG(\lambda,u_ h)\) of finite dimensional problems in the spirit of the papers of Brezzi, Rappaz and Raviart. Here, the interest is centered on double bifurcation points. It is shown how bifurcating branches are approximated by the finite dimensional solutions.
