宇宙学Einstein-Maxwell瞬子与欧几里德超对称性:超越自对偶性

Cosmological Einstein-Maxwell Instantons and Euclidean Supersymmetry: Beyond Self-Duality

M. Dunajski, J. B. Gutowski, W. A. Sabra, Paul Tod

摘要:

我们构造了具有非零宇宙学常数的Einstein-Maxwell理论的新的超对称解,并且对于该超对称解,Maxwell场强度既不是自对偶的,也不是反自对偶的。我们发现有三类解,这取决于麦克斯韦场强的符号和爱因斯坦方程中的宇宙学常数项,这些项是由Killing旋量方程的可积性条件引起的.第一类是在arXiv:0804.0009,hep-th/0406238中发现的洛伦兹超对称解的欧几里得版本。第二类是从一个三维基空间,其中承认超CR Einstein-Weyl结构。第三类是欧几里得Kastor-Traschen解。

英文摘要:

We construct new supersymmetric solutions to the Euclidean Einstein-Maxwell theory with a non-vanishing cosmological constant, and for which the Maxwell field strength is neither self-dual or anti-self-dual. We find that there are three classes of solutions, depending on the sign of the Maxwell field strength and cosmological constant terms in the Einstein equations which arise from the integrability conditions of the Killing spinor equation. The first class is a Euclidean version of a Lorentzian supersymmetric solution found in arXiv:0804.0009, hep-th/0406238 . The second class is constructed from a three dimensional base space which admits a hyper-CR Einstein-Weyl structure. The third class is the Euclidean Kastor-Traschen solution.
