Helicity Conservation via the Noether Theorem
arXiv:solv-int/9407001 · doi:10.1063/1.531123
Abstract
The conservation of helicity in ideal barotropic fluids is discussed from a group theoretical point of view. A new symmetry group is introduced i.e. the alpha group of translations. It is proven via the Noether theorem that this group generates helicity conservation.
