A. A. Coley, S. Hervik, M. N. Durkee, M. Godazgar

摘要:

有一些代数分类的时空在高维利用对齐理论,双向量和判别。以前的工作给出了一组必要条件的判别式的时空是一个特定的代数类型。我们证明了判别方法,通过应用技术的Sorkin-Gross-Perry孤子,超对称和双自旋的黑环和其他一些高维时空。我们表明,即使在一些非常复杂的度量的情况下,它是可以计算相关的判别式,并从中提取有用的信息。

英文摘要:

There are a number of algebraic classifications of spacetimes in higher dimensions utilizing alignment theory, bivectors and discriminants. Previous work gave a set of necessary conditions in terms of discriminants for a spacetime to be of a particular algebraic type. We demonstrate the discriminant approach by applying the techniques to the Sorkin-Gross-Perry soliton, the supersymmetric and doubly-spinning black rings and some other higher dimensional spacetimes. We show that even in the case of some very complicated metrics it is possible to compute the relevant discriminants and extract useful information from them.
