论文摘要
考虑了配备无效字符串的4维空间。假定一个空间承认扩大自偶联null弦的一致性，而其自动张量的自动脉冲部分在代数上是归化的。分析了不同的petrov-penrose类型的此类空间。特别注意Para-Kähler爱因斯坦空间。在所有通用性中都可以发现所有具有代数归化的自偶旋转旋转器的空间的para-kähler爱因斯坦指标。
4-dimensional spaces equipped with congruences of null strings are considered. It is assumed that a space admits a congruence of expanding self-dual null strings and its self-dual part of the Weyl tensor is algebraically degenerate. Different Petrov-Penrose types of such spaces are analyzed. A special attention is paid to para-Kähler Einstein spaces. All para-Kähler Einstein metrics of spaces with algebraically degenerate self-dual Weyl spinor are found in all the generality.
