我们考虑与pp波背景相关的矩阵模型，构造了超对称膜。除了保留16种超对称的球形膜外，还可以构造保留8种超对称的旋转椭圆膜。另一个分支描述了一般旋转1/8 BPS的双曲膜。当角动量消失时，超曲膜变成1/4 BPS，保持8个真正的超对称。它可能具有ads2或ds2的形状嵌入在平坦的三维空间中。我们研究了双曲膜上世界体积场的谱，证明了双曲膜上不存在无质量度。我们还计算了0-2字符串的谱。
We consider the matrix model associated with pp-wave background and construct supersym-metric branes. In addition to the spherical membrane preserving 16 supersymmetries, one may construct rotating elliptic membranes preserving 8 supersymmetries. The other branch describes rotating 1/8 BPS hyperbolic branes in general. When the angular momentum vanishes, the hyper-bolic brane becomes 1/4 BPS preserving 8 real supersymmetries. It may have the shape of AdS 2 or dS 2 embedded in the flat three space. We study the spectrum of the worldvolume fields on the hyperbolic branes and show that there are no massless degrees. We also compute the spectrum of the 0-2 strings.
