We find the Laughlin states of the electrons on the Poincar\acutee half-plane in different representations. In each case we show that a quantum group suq(2) symmetry exists such that the Laughlin states are a representation of it. We calculate the corresponding filling factor by using the plasma analogy of the fractional quantum Hall effect.
