Abstract: In the first part of this talk, we demonstrate a nontrivial check of Klebanov and Polyakov conjecture relating Vasiliev's higher spin gauge theory in AdS4 and free/critical O(N) vector model in three dimensions, by matching three point functions. In the second part of the talk, we propose a new conjecture relating a more general class of higher spin theories without parity symmetry in the bulk to critical Chern-Simons-fermion theories, and provide nontrivial evidences for this conjecture.
