Vu's distinct singular values conjecture for random symmetric Bernoulli matrices
Let be a random symmetric matrix with Bernoulli entries.
Vu's distinct singular values conjecture. With probability , all the singular values of are distinct.
This conjecture is motivated by the study of repeated singular values of random symmetric matrices. The paper proves a strong quantitative version for singular values in a bulk portion of the spectrum, but the full statement remains unresolved.
