论文摘要
我们研究了与大约保守的肠电流相关的对称原理，该电流负责非相对论$ 2+1 $维度湍流中的反向{能量}级联反应。我们这样做是通过在最近实现的水力动力学有效的作用原理中识别与肠流的意外对称性。我们的分析涉及相对论和非相对论的有效行动及其相关的对称性。
We study symmetry principles associated with the approximately conserved enstrophy current, responsible for the inverse {energy} cascade in non relativistic $2+1$ dimensional turbulence. We do so by identifying the accidental symmetry associated with enstrophy current conservation in a recently realized effective action principle for hydrodynamics. Our analysis deals with both relativistic and non relativistic effective actions and their associated symmetries.
