Query: Freeness of adjoint linear systems on threefolds with non Gorenstein
  Q-factorial terminal singularities or some quotient singularities   We define and calculate the weighted multiplicities of non Gorenstein
terminal singularities on threefolds and some quotient singularities. We
improve freeness conditions on threefolds.
