摘要：
Some insight is offered into the dimensional dependence of the Wentzel-Kramers-Brillouin (WKB) and improved-WKB approximations introduced by Steiner in connection with hyperspherical (originally circular) quantum billiards. The accuracy of every new D-dimensional picture is estimated by examining the residues of the spectral zeta-function poles. (C) 1995 American Institute of Physics.
