General structure and properties of higher-spin gauge theory will
be sketched with some emphasize on the unfolded dynamics approach
that underlies nonlinear higher-spin field equations. Recent
developments in higher-spin gauge theory will be briefly...
In the large N_c QCD, it is expected that the generic finite
density ground state breaks translational invariance. In this talk,
I will show a spatially modulated instability exists in the
Sakai-Sugimoto model.
We find and study the gravity duals of the supersymmetric vacua of
mass-deformed N=6 Chern-Simons-matter theory for M2-branes.
Propetries of the vacua and elementary excitations are discussed.
