论文摘要
我们在背景中构建了玻色弹性和旋转无张力（null）字符串的不变性，这些背景带有杀死张量或杀死混合类型的YANO张量。这些字符串与点粒子的密切关系可以促进这一点。我们将构造应用于Minkowski和Kerr-Newman的背景。
We construct invariants for bosonic and spinning tensionless (null) strings in backgrounds that carry Killing tensors or Killing-Yano tensors of mixed type. This is facilitated by the close relation of these strings to point particles. We apply the construction to the Minkowski and to the Kerr-Newman backgrounds.
