本文研究了四维和五维中具有非平凡矢量多重态和8个超荷的阿贝尔规范超引力理论的超对称极值。这些模型的标量场参数化的歧管组成的断开的分支和限制的情况下，该歧管有一个非奇异的度量，我们表明，在每一个分支可以有最多一个极值，这是一个局部最大值（W>0）或最小值（W<0）的超势W。因此，这些超引力模型不允许在超势的不同极值之间插值的规则域壁解，并且横向于壁的时空总是渐近地接近AdS的边界（对偶场论中的UV不动点）。(c)2000年，美国物理学会。
We investigate supersymmetric extrema of Abelian gauged supergravity theories with nontrivial vector multiplets and 8 supercharges in four and five dimensions. The scalar fields of these models parametrize a manifold consisting of disconnected branches and, restricting to the case where this manifold has a nonsingular metric, we show that on every branch there can be at most one extremum, which is a local maximum (for W>0) or a minimum (for W<0) of the superpotential W. Therefore, these supergravity models do not allow for regular domain wall solutions interpolating between different extrema of the superpotential and the space-time transverse to the wall asymptotically always approaches the boundary of AdS (UV-fixed points in a dual field theory).
