The Higher Schur-Multiplicator of Certain Classes of Groups
  The paper is devoted to calculating the higher Schur-multiplicator of certain classes of groups with respect to the variety of nilpotent groups. Our results somehow generalize the works of M.R.R. Moghaddam (1979), and N.D. Gupta and M.R.R. Moghaddam (1993).
