关于随机稀疏矩阵的秩

On the Rank of Random Sparse Matrices

Kevin P. Costello, Van Vu

摘要:

本文研究随机(对称)稀疏矩阵的秩。我们的主要发现是,在这种矩阵中出现的任何依赖性都很有可能是由一组包含压倒性数量的零的几行组成的。这使我们能够获得对联合秩的精确估计。

英文摘要:

We investigate the rank of random (symmetric) sparse matrices. Our main finding is that with high probability, any dependency that occurs in such a matrix is formed by a set of few rows that contains an overwhelming number of zeros. This allows us to obtain an exact estimate for the co-rank.
