Starting with three dimensional Chern--Simons theory with gauge group $Sl(N,R)$, we derive an action $S_{cov}$ invariant under both left and right $W_N$ transformations. We give an interpretation of $S_{cov}$ in terms of anomalies, and…
A possible way of defining M theory as the CS theory for the supergroup $OSp(1|32)\times OSp(1|32)$ is investigated, based on the approach by Horava in hep-th/9712130. In the high energy limit (expansion in M), where only the highest…
We show that an extended $3D$ Schr\"odinger algebra introduced in [1] can be reformulated as a $3D$ Poincar\'e algebra extended with an SO(2) R-symmetry generator and an $SO(2)$ doublet of bosonic spin-1/2 generators whose commutator closes…
