et A be a $n\times n$ symmetric matrix with $(A_{i,j))_{i≤j}$ independent and identically distributed according to a subgaussian distribution. I will present a recent result in which we provide lower tail estimates for the least singular value of A which are tight up to a constant factor.
This is joint work with Matthew Jenssen, Marcus Michelen and Julian Sahasrabudhe.
