We consider a regular indefinite Sturm-Liouville problem with twoself-adjoint boundary conditions affinely dependent on the eigenparameter. Wegive sufficient conditions under which the root vectors of this Sturm-Liouvilleproblem can be selected to form a Riesz basis of a corresponding weightedHilbert space.
