Clebsch parameterization from the symplectic point of view

Abstract: This work propose an alternative and systematic way to obtain a canonical Lagrangian formulation for rotational systems. This will be done in the symplectic framework and with the introduction of extra variables which enlarge the phase space. In fact, this formalism provides a remarkable and new result to compute the canonical Lagrangian formulation for rotational systems, {\it i.e.}, the obstruction to the construction of a canonical formalism can be solved in an arbitrary way and, consequently, a set of dyna… Show more

“…It is well known that systems which have vorticity and/or viscosity have Casimir invariants which obstruct the construction of a canonical formalism for a fluid, as demonstrated in [52]. However, this obstruction can be eliminated using the Clebsch parameters, as it was shown by Lin [53] and by two of us in [54]. In fact, with the introduction of Clebsch parameters, it is possible to obtain a Lagrangian density for the rotational fluid with dissipation, 3-dimensional, as being…”

“…is the inverse of the symplectic matrix, this matrix can be computed by a straightforward calculation from the property r ) is given by f r, r = A( r, r ) C ( r, r ) −C( r, r ) B( r, r ) , (25) where A( r, r ), B( r, r ) and C ( r, r ) are arbitrary functions. From the properties above, the following general set of equations are obtained:…”
