    Abstract

    A framework is developed based on the concepts of divorticity B (equivalent to del x omega, omega being the vorticity) and dihelicity g (equivalent to 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 (C) 2D hydrodynamics. 2010 Elsevier B.V.
