$gl_q(n)$-covariant Oscillators and q-Deformed Quantum Mechanics in n   Dimensions
  In this paper the coherent state for $gl_q(n)$-covariant oscillators is constructed and is shown to satisfy the completeness relation. And the q-analogue of quantum mechanics in n dimensions is obtained by using $gl_q(n)$ oscillators.
