摘要：

We propose an explicit expression for vacuum expectation values of the boundary field e(ia phi B) in the boundary sine-Gordon model with zero bulk mass. This expression agrees with known exact results for the boundary free energy and with perturbative calculations. (C) 1997 Elsevier Science B.V.
