论文摘要
我们构建了棉花纺纱厂和拓扑质理论的双磁场强度旋转器之间的双复制关系，作为Weyl双拷贝的三维类似物。该关系在弯曲的背景下用于波解决方案。我们给出了n型空间的明确证明，并显示满足棉花双复制的例子。
We construct a double copy relation between the Cotton spinor and the dual field strength spinor of topologically massive theories, as the three-dimensional analogue of the Weyl double copy. The relationship holds in curved backgrounds for wave solutions. We give an explicit proof for Type N spacetimes and show examples satisfying the Cotton double copy.
