Abstract

Let $\boldsymbol{X}_1, \cdots, \boldsymbol{X}_{m_n}$ be independent $n\times n$ complex Ginibre ensembles and $Z_1, \cdots,$ $ Z_n$ be the eigenvalues of $\prod_{j=1}^{m_n} \boldsymbol{X}_j.$ Suppose $\lim\limits_{n\to\infty}m_n=+\infty,$ we obtain large and moderate deviations for $\max_{1\le i\le n} \log |Z_i|.$
