Random symmetric matrices: rank distribution and irreducibility of the characteristic polynomial

Asaf Ferber, Vishesh Jain, Ashwin Sah +1

Conditional on the extended Riemann hypothesis, we show that with high probability, the characteristic polynomial of a random symmetric ${\pm 1}$ -matrix is irreducible. This addr…

Rank deficiency of random matrices

Vishesh Jain, Ashwin Sah, Mehtaab Sawhney

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