论文摘要
在本文中，我们考虑了$ aDS_3 \ times s^3 \ times s^3 \ times t^4 $背景的$ IIB $ $ supergravity理论的非亚伯t二几何形状，沿便利的$ su（2）$ so（4）$ r-r-symmetry。我们研究了由此产生的大规模$ IIA $ Supergravity理论的各种无效的测量学，并研究了沿这些大地测量学的Penrose限制。我们发现，由此产生的背景之一允许在合适的零用测量物附近的PP波浪几何形状。我们对产生的PP波几何形状进行超对称分析，并观察到它保留了16个增压。此外，我们评论了由此产生的PP波背景的可能的量规理论双重。
In this paper we consider the non-Abelian T-dual geometry of the type $IIB$ supergravity theory on $AdS_3\times S^3\times T^4$ background along a convenient $SU(2)$ subgroup of the $SO(4)$ R-symmetry. We examine various null geodesics of the resulting massive type $IIA$ supergravity theory and investigate the Penrose limits along these geodesics. We find that one of the resulting backgrounds admits pp-wave geometry in the neighbourhood of a suitable null geodesic. We carry out the supersymmetry analysis of the resulting pp-wave geometry and observe that it preserves sixteen supercharges. Further we comment on the possible gauge theory dual of the resulting pp-wave background.
