    Abstract:
    Consideration is given to the evolution of stationary axisymmetric
    rotating Kerr naked singularities due to the accretion of matter from
    thin corotating disks. Within the framework of the Page-Thorne model of
    accretion disks, it is shown that the naked singularity must evolve
    towards an extreme black hole state provided sufficient mass is
    accreted. Analytical expressions for the time evolution of the Kerr
    naked singularity as a function of initial mass and angular momentum are
    then obtained for the cases of a constant accretion rate, an accretion
    rate proportional to black hole mass, and an accretion rate self-
    regulated at the critical rate. It is pointed out that for accretion in
    binary systems, singularities of mass less than 10 solar masses may be
    converted into black holes only for angular momentum very close to
    unity. Effects of the capture of the radiation emitted by the disk by
    the singularity or the disk itself and of changes in disk geometry at
    the later stages of black hole conversion are also considered
