It has previously been conjectured that the theory of free fundamental
scalars minimally coupled to a Chern Simons gauge field is dual to the theory
of critical fundamental fermions minimally coupled to a level rank dual Chern
Simons gauge field. ...

In this paper we discuss SU(N) Chern-Simons theories at level k with both

We investigate BPS solutions in ABJM theory on RxS^2. We find new BPS
