Light-cone decomposition of a massive two-form
= Light-cone decomposition of a massive two-form
{title2=$A_{-i},\ A_{ij}$}
If $\partial_-$ is invertible, the divergence constraint of a <massive two-form field> makes $A_{-i}$ and $A_{ij}$ independent. It gives $A_{+-}=-\partial_-^{-1}\partial_iA_{-i}$ and $A_{+i}=\partial_-^{-1}(-\partial_+A_{-i}+\partial_jA_{ji})$. All independent components obey the <Klein-Gordon equation>. Their count is $(D-2)+\binom{D-2}{2}=\binom{D-1}{2}$.
