摘要
Massive Yang-Mills fields and Lagrange multiplier fields are quantized by the modified Faddeev-Jackiw quantization method, and the method's comparisons with Dirac method and the Usual Faddeev-Jackiw method are also given. We show that this method not only is equivalent to Dirac method, but also remains all the virtues of the usual Faddeev-Jackiw method. Moreover, the modified Faddeev-Jackiw quantization method is simpler than the usual one when obtaining new secondary constraints. Therefore, the modified Faddeev-Jackiw method is more economical and effective than Dirac method and the usual Faddeev-Jackiw method. Meanwhile, we find the new meanings of the Lagrange multipliers, and discover that the Lagrange multipliers and the zeroth components of gauge held are just a pair of canonical field variables except a constant factor in this system.
