DLCQ-M(atrix) description of string theory, and supergravity [PDF]
Nuclear Physics B, 1998 We discuss the connection between Matrix string theory and the DLCQ of string theory. Using this connection we describe the sense in which perturbative string amplitudes are reproduced in the Matrix string theory. Using recent realization of the connection between SYM and Supergravity, we suggest how to describe Matrix theory with non-flat backgrounds.

A supersymmetric SYK model with a curious low energy behavior
Journal of High Energy PhysicsWe consider N $$ \mathcal{N} $$ = 2, 4 supersymmetric SYK models that have a peculiar low energy behavior, with the entropy going like S = S 0 + (constant)T a , where a ≠ 1.

Chaos from equivariant fields on fuzzy S 4
Journal of High Energy Physics, 2018 We examine the 5d Yang-Mills matrix model in 0 + 1-dimensions with U(4N) gauge symmetry and a mass deformation term. We determine the explicit SU(4) ≈ SO(6) equivariant parametrizations of the gauge field and the fluctuations about the classical four ...

Bootstrap bounds on D0-brane quantum mechanics
Journal of High Energy Physics, 2023 We derive simple bootstrap bounds on correlation functions of the BFSS matrix theory/D0-brane quantum mechanics. The result strengthens and extends Polchinski’s virial theorem bound to finite energies and gives the first non-trivial bound on ⟨Tr X 2 ...

Proposal of a topological M(atrix) theory [PDF]
Physical Review D, 1999 Keeping in mind the several models of M(atrix) theory we attempt to understand the possible structure of the topological M(atrix) theory ``underlying'' these approaches. In particular we are motivated by the issue about the nature of the structure of the vacuum of the topological M(atrix) theory and how this could be related to the vacuum of the ...

Introduction to M(atrix) theory and noncommutative geometry [PDF]
Physics Reports, 2002 Noncommutative geometry is based on an idea that an associative algebra can be regarded as "an algebra of functions on a noncommutative space". The major contribution to noncommutative geometry was made by A. Connes, who, in particular, analyzed Yang-Mills theories on noncommutative spaces, using important notions that were introduced in his papers ...

General Relativity in IIB matrix model
Journal of High Energy PhysicsThe matrix models are non-perturbative formulations of string theory, from which many believe that spacetime arises. The matrix fluctuations around the spacetime thus created should represent both matter and gravitational fields.

Long string scattering in c = 1 string theory
Journal of High Energy Physics, 2019 We study the scattering of long strings in c = 1 string theory, both in the worldsheet description and in the non-singlet sector of the dual matrix quantum mechanics. From the worldsheet perspective, the scattering amplitudes of long strings are obtained

From Wrapped Supermembrane to M(atrix) Theory From Wrapped Supermembrane to M(atrix) Theory
, 2002 The issue of justifying the matrix-theory proposal is revisited. We first discuss how the matrix-string theory is derived directly starting from the eleven dimensional supermembrane wrapped around a circle of radius $R=g_s\ell_s$, without invoking any stringy assumptions, such as S- and T-dualities. This derivation provides us a basis for studying both
