Idea

The ABJM model (ABJM 08) is an 𝒩=6\mathcal{N} = 6 3d superconformal gauge field theory involving Chern-Simons theory with gauge group SU(N) and coupled to matter fields. For Chern-Simons level kk it is supposed to describe the worldvolume theory of NN coincident black M2-branes at an /k\mathbb{Z}/k-cyclic group orbifold singularity with near-horizon geometry AdS 4×S 7/(/k)AdS_4 \times S^7/(\mathbb{Z}/k) (see at M2-branes – As a black brane).

6d superconformal gauge field theory

(Shnider 88, also Nahm 78, see Minwalla 98, section 4.2)

For k=2k = 2 the supersymmetry of the ABJM model increases to 𝒩=8\mathcal{N} = 8. For k=2k = 2 and N=2N = 2 the ABJM model reduces to the BLG model (ABJM 08, section 2.6).

Due to the matter coupling, the ABJM model is no longer a topological field theory as pure Chern-Simons is, but it is still a conformal field theory. As such it is thought to correspond under AdS-CFT duality to M-theory on AdS4 ×\times S7//k\mathbb{Z}/k (see also MFFGME 09).

Notice that the worldvolume SU(N)SU(N) gauge group enhancement at an k\mathbb{Z}_k-ADE singularity is akin to the gauge symmetry enhancement of the effective field theory for M-theory on G2-manifolds at the same kind of singularities (see at M-theory on G2-manifolds – Nonabelian gauge groups).

More generally, classification of the near horizon geometry of smooth (i.e. non-orbifold) 12\geq \tfrac{1}{2} BPS black M2-brane-solutions of the equations of motion of 11-dimensional supergravity shows that these are the Cartesian product AdS 4×(S 7/G)AdS_4 \times (S^7/G) of 4-dimensional anti de Sitter spacetime with a 7-dimensional spherical space form S 7/G^S^7/{\widehat{G}} with spin structure and N4N \geq 4, for G^\widehat{G} a finite subgroup of SU(2) (MFFGME 09, see here).

Properties

AdS/CFT duality

Under holographic duality supposed to be related to M-theory on AdS 4×S 7/ kAdS_4 \times S^7 / \mathbb{Z}_k.

Boundary conditions
