Abstract

Consider the square random matrix An=(aij)n,nA_n=(a_{ij})_{n,n}, where {aij:=aij(n),i,j=1,,n}\{a_{ij}:=a_{ij}^{(n)},i,j=1,\ldots,n\} is a collection of independent real random variables with means zero and variances one. Under the additional moment condition supnmax1i,jnEaij4<,\sup_n\max_{1\leq i,j\leq n}\mathbb{E}a_{ij}^4<\infty, we prove Girko's logarithmic law of detAn\det A_n in the sense that as nn\rightarrow\infty \begin{eqnarray*}\frac{\log|\det A_n|-(1/2)\log(n-1)!}{\sqrt{(1/2)\log n}}\stackrel{d}{ \longrightarrow}N(0,1).\end{eqnarray*}
