Abstract:We present a generalization of the six-dimensional (2, 0) system of arXiv:1007.2982 to include a constant abelian 3-form. For vanishing 3-form this system is known to provide a variety descriptions of parallel M5-branes. For a particular choice of 3-form the system is shown to reduce to that of two M2-branes. Thus this generalised (2, 0) system provides a unified description of two parallel M2-branes or M5-branes.
“…The on-shell conditions now reduce to motion on the moduli space of solutions to the Hitchin System, this time for any gauge group. However although it has the same number of supersymmetries as the M2-brane case discussed above it only has SO(2) × SO(5) R-symmetry, not SO(2) × SO (6). It is natural to postulate that, just as the lorentzian M2-brane theory is the strong coupling limit of (2+1)-dimensional maximally supersymmetric Yang-Mills (which can be viewed as the dimensional reduction of the M5-brane), the null M2-brane theory (2.5) is the strong coupling fixed point of the null M5-brane action (3.20) in the case of an SU(2) gauge group.…”

We present lagrangian gauge theories in 2+1 and 4+1 dimensions with 16 supersymmetries which are invariant under rotations and translations but not boosts. The on-shell conditions reduce the dynamics to motion on a moduli space of BPS states graded by a topologically conserved quantity. On each component of the moduli space only half the supersymmetry is realised. We argue that these theories describe M2branes and M5-branes which have been infinitely boosted so that their worldvolume 'time' has become null. *

“…Finally in this last section I wanted to indulge myself by reporting on my own recent work that I hope is of interest to the conference crowd and I welcome any suggestions. In particular in [60,61] my collaborators and I constructed a representation of the (2,0) superalgebra acting on a set of fields:…”

In this talk we will review the construction of M2‐brane SCFT's highlighting some novelties and the role of 3‐algebras. Parts of our discussion will closely follow parts of [1]. Next we will discuss M5‐branes: the basics, the obstacles as well as various attempts to construct the associated SCFT and potential relations between M2‐branes and M5‐branes.
Abstract:We study splitting and joining interactions of giant gravitons with angular momenta N 1/2 J N in the type IIB string theory on AdS 5 × S 5 by describing them as instantons in the tiny graviton matrix model introduced by Sheikh-Jabbari. At large J the instanton equation can be mapped to the four-dimensional Laplace equation and the Coulomb potential for m point charges in an n-sheeted Riemann space corresponds to the m-to-n interaction process of giant gravitons. These instantons provide the holographic dual of correlators of all semi-heavy operators and the instanton amplitudes exactly agree with the pp-wave limit of Schur polynomial correlators in N = 4 SYM computed by Corley, Jevicki and Ramgoolam.By making a slight change of variables the same instanton equation is mathematically transformed into the Basu-Harvey equation which describes the system of M2-branes ending on M5-branes. As it turns out, the solutions to the sourceless Laplace equation on an nsheeted Riemann space correspond to n M5-branes connected by M2-branes and we find general solutions representing M2-branes ending on multiple M5-branes. Among other solutions, the n = 3 case describes an M2-branes junction ending on three M5-branes. The effective theory on the moduli space of our solutions might shed light on the low energy effective theory of multiple M5-branes.
