标题： Another Conjecture about M(atrix) Theory

摘要： 目前对M(atrix)理论的理解是，在大N极限下，某些超对称Yang Mills理论与无限动量框架下的M理论等价。 在本文中提出了一个假设，即M理论与M(atrix)理论之间的等价性不仅限于大N极限，而是适用于有限N。认为存在一种轻锥描述，其中其中一个轻锥坐标被周期性地识别。 在轻锥文献中，这被称为离散轻锥量子化（DLCQ）。 在此框架中，对于纵向动量的每个量化值N，都存在精确的轻锥描述。 新的假设指出，M理论的DLCQ部分由U(N)矩阵理论精确描述。 提出了支持该假设的证据。 显示英文摘要

摘要： 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 the conjecture is put forward that the equivalence between M and M(atrix) theory is not limited to the large N limit but is valid for finite N. It is argued that a light cone description of M-theory exists in which one of the light like coordinates is periodically identified. In the light cone literature this is called Discrete Light Cone Quantization (DLCQ). In this framework an exact light cone description exists for each quantized value N of longitudinal momentum. The new conjecture states that the sector of the DLCQ of M-theory is exactly described by a U(N) matrix theory. Evidence is presented for the conjecture.
