On the singularity probability of random Bernoulli matrices

组合数学 2008-08-06 v2

摘要

Let nn be a large integer and MnM_n be a random nn by nn matrix whose entries are i.i.d. Bernoulli random variables (each entry is ±1\pm 1 with probability 1/2). We show that the probability that MnM_n is singular is at most (3/4+o(1))n(3/4 +o(1))^n, improving an earlier estimate of Kahn, Koml\'os and Szemer\'edi, as well as earlier work by the authors. The key new ingredient is the applications of Freiman type inverse theorems and other tools from additive combinatorics.
