Asymptotics of the partition function of a Laguerre-type random matrix
model    [PDF]

Yi Zhao, Lihua Cao, Dan Dai

We study asymptotics of the partition function $Z_N$ of a Laguerre-type random matrix model when the matrix order $N$ tends to infinity. By using the Deift-Zhou steepest descent method for Riemann-Hilbert problems, we obtain an asymptotic expansion of $\log Z_N$ in powers of $N^{-2}$.
