Abstract

Fix q and let M_n be an n x n matrix with entries drawn independently from the finite field F_q according to some distribution μ_n. It is shown that, except in certain pathological cases, the probability that M_n is nonsingular is asymptotically the same as for uniform entries; that is, Pr(M_n is nonsingular) Π_i≥1 (1 - q^-i) as n → ∞.
