具有拓扑项的七维引力

Seven-Dimensional Gravity with Topological Terms

H. Lu, Yi Pang

摘要:

我们通过在爱因斯坦-希尔伯特作用量上增加两个拓扑项来构造新的七维引力。对于某些耦合常数的选择,这些项可能与对11维超引力的3型场方程的R^4修正有关。我们导出了运动方程的全部方程组。我们发现静态球对称黑洞不受拓扑项的影响。我们得到了压缩的AdS_7,并在欧氏签名中压缩了7个球面和Q^{111}空间.

英文摘要:

We construct new seven-dimensional gravity by adding two topological terms to the Einstein-Hilbert action. For certain choice of the coupling constants, these terms may be related to the R^4 correction to the 3-form field equation of eleven-dimensional supergravity. We derive the full set of the equations of motion. We find that the static spherically-symmetric black holes are unmodified by the topological terms. We obtain squashed AdS_7, and also squashed seven spheres and Q^{111} spaces in Euclidean signature.
