We propose a M(atrix) model for N=4 $SU(k)$ Super-Yang-Mills theory compactified on $T^4$. In this model it is possible to make $T^4$ noncommutative and it is easy to turn on all 6 components of the noncommutativity on $T^4$. The action of S-duality on the noncommutativity parameters is also manifest. The M(atrix)-model is given by the large $N$ limit of a $\sigma$-model on $T^2$ whose target space is the moduli space of $k$ SU(N) instantons on $T^3\times R$. We also propose that the $SU(k)$ 2… Expand

A Matrix Model for the Null-Brane
The null-brane background is a simple smooth 1/2 BPS solution of string theory. By tuning a parameter, this background develops a big crunch/big bang type singularity. We construct the DLCQExpand

On Noncommutative Open String Theories
We investigate new compactifications of OM theory giving rise to a 3+1 dimensional open string theory with noncommutative $x^0$-$x^1$ and $x^2$-$x^3$ coordinates. The theory can be directly obtainedExpand
Two conjectures on gauge theories, gravity, and infinite dimensional Kac-Moody groups
We propose that the structure of gauge theories, the (2,0) and little-string theories is encoded in a unique function on the real group manifold E10(R). The function is invariant under the maximalExpand
Branes, Fluxes and Duality in M(atrix)-Theory
We use the T-duality transformation which relates M-theory on T^3 to M-theory on a second T^3 with inverse volume to test the Banks-Fischler-Shenker-Susskind suggestion for the matrix modelExpand
Witten index and threshold bound states of D-branes
We consider the Witten index I = Tr(−1)F of SU(2) super Yang-Mills quantum mechanics (SYMQ) with N = 16, 8, 4 supersymmetries. The theory governs the interactions between a pair of D-branes underExpand
The Large-N Limit of Superconformal Field Theories and Supergravity

Another Conjecture about M(atrix) Theory
The current understanding of M(atrix) theory is that in the large N limit certain supersymmetric Yang Mills theories become equivalent to M-theory in the infinite momentum frame. In this paper theExpand
Multi-instanton calculus and the AdS/CFT correspondence in N = 4 superconformal field theory
Abstract We present a self-contained study of ADHM multi-instantons in SU(N) gauge theory, especially the novel interplay with supersymmetry and the large-N limit. We give both field- andExpand
ON THE TWISTED (2,0) AND LITTLE-STRING THEORIES
Abstract We study the compactification of the (2, 0) and type-II little-string theories on S 1 , T 2 and T 3 with an R-symmetry twist that preserves half the supersymmetry. We argue that it producesExpand
On theories with light-like noncommutativity
We show that field theories with light-like noncommutativity, that is with θ0i = -θ1i, are unitary quantum theories, and that they can be obtained as decoupled field theory limits of string theoryExpand
String theory and noncommutative geometry
We extend earlier ideas about the appearance of noncommutative geometry in string theory with a nonzero B-field. We identify a limit in which the entire string dynamics is described by a minimallyExpand
