摘要：
We study the U-q(<(sl(n))over cap>) analogue of the XXZ spin chain with a boundary magnetic field h. We construct explicit bosonic formulas of the vacuum vector and the dual vacuum vector with a boundary magnetic field. For an application of the explicit formula of the vacuum vector, we derive the integral representation of the boundary spontaneous magnetization. (C) 2000 American Institute of Physics.
