Abstract:

We solve the problem on local statistics of finite Lyapunov exponents for M products of N×N Gaussian random matrices as both M and N go to infinity, proposed by Akemann, Burda, Kieburg and Deift. When the ratio (M+1)/N changes from 0 to ∞, we prove that the local statistics undergoes a transition from GUE to Gaussian. Especially at the critical scaling (M+1)/N → γ ∈ (0,∞), we observe a phase transition phenomenon.
