Abstract.We approximate solution of generalized equations in a Banach spaces. We provide sufficient conditions for the local convergence of a family of two-step Steffensen-type algorithms using a fixed points theorem of multiapplications, the usual Hölder continuous condition and the Aubin continuous concept. This study follows the recent result of two-step Steffensen's method related to the resolution of nonlinear equations (see [#!amat!#]).
