Constraint structure in modified Faddeev-Jackiw method
We show that in modified Faddeev-Jackiw formalism, first and second class
constraints appear at each level, and the whole constraint structure is in
exact correspondence with level by level method of Dirac formalism.Comment: 11 pages, No figure
Classification of constraints using chain by chain method
We introduce "chain by chain" method for constructing the constraint
structure of a system possessing both first and second class constraints. We
show that the whole constraints can be classified into completely irreducible
first or second class chains. We found appropriate redefinition of second class
constraints to obtain a symplectic algebra among them.Comment: 23 pages, to appear in Int. J. Mod. Phys.
