Constraint structure in modified Faddeev-Jackiw method

TL;DR

This paper demonstrates that the modified Faddeev-Jackiw formalism accurately reproduces the constraint structure of Dirac's method, with first and second class constraints appearing at each level.

Contribution

It establishes a precise correspondence between the modified Faddeev-Jackiw and Dirac formalisms in analyzing constraint structures.

Findings

First and second class constraints appear at each level in the modified Faddeev-Jackiw formalism.

The entire constraint structure matches the level-by-level Dirac method.

The formalism provides a consistent framework for constraint analysis.

Abstract

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.
