Light-cone M5 and multiple M2-branes
نویسندگان
چکیده
We present the light-cone gauge fixed Lagrangian for the M5-brane; it has a residual ‘exotic’ gauge invariance with the group of 5-volume preserving diffeomorphisms, SDiff5, as gauge group. For an M5-brane of topology R 2 ×M3, for closed 3-manifold M3, we find an infinite tension limit that yields an SO(8)-invariant (1 + 2)-dimensional field theory with ‘exotic’ SDiff3 gauge invariance. We show that this field theory is the Carrollian limit of the Nambu bracket realization of the ‘BLG’ model for multiple M2-branes. 1 [email protected]. Address after July 1: † Dept of Theor.

M2-branes stretching between M5-branes
A generalization of Nahm’s equation has been recently conjectured by Basu and Harvey to be the BPS condition describing the bound state of a stack of M2branes ending on an M5-brane. In this note exact solutions are presented for the proposed BPS equation – which is from the point of view of the M2-brane world-volume dynamics – with boundary conditions appropriate for M2-branes stretching betwee...
متن کاملGravity Duals of Fractional Branes in Various Dimensions
We derive type II supergravity solutions corresponding to space-filling regular and fractional Dp branes on (9− p)-dimensional conical transverse spaces. Fractional Dp-branes are wrapped D(p + 2)-branes; therefore, our solutions exist only if the base of the cone has a non-vanishing Betti number b2. We also consider 11-dimensional SUGRA solutions corresponding to regular and fractional M2 brane...
متن کاملIntersecting Noncommutative M5-branes from Covariant Open Supermembrane
We study intersecting noncommutative (NC) M5-branes from κ-invariance of an open supermembrane action with constant three-form fluxes. The κ-invariance gives rise to possible D-brane configurations for which projection operators can be determined. We construct projection operators for two types of 1/4 BPS intersecting NC M5-branes. The one is an intersection of two NC M5-branes: NC M5⊥NC M5 (3)...
متن کاملA scan of universal breathing-mode reductions
The near horizon limits of M2 and D3 branes probing special holonomy cones give rise to supersymmetric AdS4 × M7 and AdS5 × M5 solutions of D = 11 and type IIB supergravity, respectively, where M7 and M5 are special types of Einstein spaces. Here we will show the existence of consistent Kaluza-Klein truncations of D = 11 and type IIB supergravity on such M7 and M5 down to matter-coupled supergr...
متن کاملA note on half-supersymmetric bound states in M-theory and type IIA
By using O(7, 7) transformations, to deform D6–branes, we obtain half-supersymmetric bound state solutions of type IIA supergravity, containing D6, D4, D2, D0, F1-branes and waves. We lift the solutions to M-theory which gives half-supersymmetric M-theory bound states, e.g. KK6–M5–M5–M5–M2–M2–M2–MW. We also take near horizon limits for the type IIA solutions, which gives supergravity duals of 7...
