Description
A framework is developed based on the concepts of divorticityB (≡∇xω, ω being the vorticity) and dihelicity g(≡v.B) for discussing the theoretical structure underlying two-dimensional (2D) hydrodynamics. This formulation leads to the global and Lagrange invariants that could impose significant constraints on the evolution of divorticity lines in 2D hydrodynamics.
