Query: Finite-dimensional representations of U_q[gl(2/1)] in a basis of
  U_q[gl(2)\oplus gl(1)]   The quantum superalgebra $U_q[gl(2/1)]$ is given as both a Drinfel'd--Jimbo
deformation of $U[gl(2/1)]$ and a Hopf superalgebra. Finite--dimensional
representations of this quantum superalgebra are constructed and investigated
in a basis of its even subalgebra $U_q[gl(2)\oplus gl(1)]$. The present method
for constructing representations of a quantum superalgebra combines previously
suggested ones for the cases of superalgebras and quantum superalgebras, and,
therefore, has an advantage in comparison with the latter.
