最一般的球对称M2-branes和IIB型字符串

Most General Spherically Symmetric M2-branes and Type IIB Strings

Zhao-Long Wang, H. Lu

摘要:

我们得到了最一般的球对称M2-膜和IIB型弦,它们分别具有\R^{1,2} \times SO(8)和\R^{1,1} \times SO(8)等距.我们发现有12种不同的M2-膜,并研究了它们的曲率性质。特别地,我们得到了连接两个渐近区域的新的光滑M2膜虫孔:一个是平坦的,另一个可以是平坦的,也可以是AdS_4 \times S ^[7]。我们发现这些虫洞是可以穿越某些类时轨迹的。利用\R^{1,1} \times SO(3)等距,我们还得到了最一般的五维Ricci平坦解.

英文摘要:

We obtain the most general spherically symmetric M2-branes and type IIB strings, with \R^{1,2}\times SO(8) and \R^{1,1}\times SO(8) isometries respectively. We find that there are twelve different classes of M2-branes, and we study their curvature properties. In particular we obtain new smooth M2-brane wormholes that connect two asymptotic regions: one is flat and the other can be either flat or AdS_4\times S^7. We find that these wormholes are traversable with certain time-like trajectories. We also obtain the most general Ricci-flat solutions in five dimensions with \R^{1,1}\times SO(3) isometries.
