论文摘要
我们将所有剩下的伪式伪里曼尼亚人的爱因斯坦度量标准在$ \ mathrm {sl}(2,\ mathbb {r})\ times \ times \ times \ times \ times \ mathrm {sl}(2,\ mathbb {r})$下,这是一个单位式的,在一个单位范围内。我们发现,恰好有两个这样的指标,直到同型,杀戮形式和几乎是伪卡勒指标。
We classify all left-invariant pseudo-Riemannian Einstein metrics on $\mathrm{SL}(2,\mathbb{R})\times \mathrm{SL}(2,\mathbb{R})$ that are bi-invariant under a one-parameter subgroup. We find that there are precisely two such metrics up to homothety, the Killing form and a nearly pseudo-Kähler metric.
