@QuantumDot Read Wess-Bagger. The answer is there.

comment Is there a theorem that says that QFT reduces to QM in a suitable limit? A theorem similar to Ehrenfest's theorem?
@Prathyush Ask as a separate question. That's how stackexchange works.

comment About 2+1 dimensional superconformal algebra
Now that you understand that point, I think you should stop asking and think for several days by yourself. Good luck!

comment About 2+1 dimensional superconformal algebra
You need to distinguish two questions: what is the representation of the supercharge and what is the representation of the quantum states the supercharge is acting on. In order to get the inequality you're interested, you need to consider the latter question. You can't fix $I$ to be $N\times N$ and $M_{\mu\nu}$ to be $2\times 2$. They depend on $h$ and $j$. You try extracting $j$ from the $M_{\mu\nu}$ you already fixed, but that's not the point. $j$ depends on the quantum states.

2) Right. 3) The author didn't say Gamma are all real, he just said sigma is real. 4) You need to understand that the matrices M are determined by j and that the metrices $I$ are detemined by h.

1) The right matrices to use depend on the quantum states. What you wrote down is not OK even in a single superconformal multiplet. How did you determine which matrix representations of SO(N) and SO(2,1) to use?
