Parametrized Hamiltonian Stationary Legendrian Varifolds into the Heisenberg Group H² -- The Sequential Weak Closure

We establish fundamental properties satisfied by Parametrized Hamiltonian Stationary Legendrian Varifolds into the Heisenberg Group. Among other properties we prove the sequential weak closure of this space under local area control, finite topology control and conformal class control. This work is the second part of a project launched in 13 about the realisation by Hamiltonian stationary surfaces of any arbitrary non trivial minmax operations on the area among Legendrian surfaces in every closed Sasaki-Einstein 5 dimensional manifold.
