我们给出了IKKT型矩阵模型的简单解，描述了一个量子化的均匀和各向同性的宇宙学，k=− 1，有限的微观态密度和一个解析的大爆炸。后来，人们得到了一个线性的惯性宇宙学a（t）t，它非常接近于观测。该解决方案由两张相反的内在手征，这是连接在一个欧几里德前大爆炸时代。
We present simple solutions of IKKT-type matrix models describing a quantized homogeneous and isotropic cosmology with k=− 1, finite density of microstates and a resolved Big Bang. At late times, a linear coasting cosmology a (t)∝ t is obtained, which is remarkably close to observation. The solution consists of two sheets with opposite intrinsic chiralities, which are connected in a Euclidean pre-big bang era.
