Small-scale clumps of dark matter
  Small-scale clumps of dark matter are gravitationally bounded structures that
have masses comparable to or lower than stellar masses and consist of
noninteracting or weakly interacting dark matter particles. In this paper, the
current knowledge about the formation and evolution of such structures is
reviewed, various types of spectra of primordial cosmological perturbations are
considered, and various dark matter models are discussed. Depending on the
particular spectrum type, dark matter clumps may differ considerably in their
formation processes and ultimate characteristics. The role of clumps in
experiments on indirect detection of dark matter particles via their
annihilation products is discussed. A number of astrophysical problems and
phenomena that are related to dark matter clumps are examined.
