摘要

设$M_n$是具有i.i.d.$\text｛Bernoulli｝（1/2）$条目的随机$n\timesn$矩阵。我们证明了对于固定的$k\ge1$，\[\lim_｛n\to\infty｝\frac｛1｝｛n｝\log_2\mathbb｛P｝[\text｛corank｝M_n\gek]=-k

Rank deficiency of random matrices

Let $M_n$ be a random $n\times n$ matrix with i.i.d. $\text{Bernoulli}(1/2)$ entries. We show that for fixed $k\ge 1$, \[\lim_{n\to \infty}\frac{1}{n}\log_2\mathbb{P}[\text{corank }M_n\ge k] = -k.\]

期刊介绍： The Electronic Communications in Probability (ECP) publishes short research articles in probability theory. Its sister journal, the Electronic Journal of Probability (EJP), publishes full-length articles in probability theory. Short papers, those less than 12 pages, should be submitted to ECP first. EJP and ECP share the same editorial board, but with different Editors in Chief.
