Resurgence relation and global asymptotic analysis of orthogonal polynomials via the Riemann-Hilbert approach

A global asymptotic analysis of orthogonal polynomials via the Riemann-Hilbert approach is presented, with respect to the polynomial degree. The domains of uniformity are described in certain phase variables. A resurgence relation within the sequence of Riemann-Hilbert problems is observed in the procedure of derivation. Global asymptotic approximations are obtained in terms of the Airy function. The system of Hermite polynomials is used as an illustration.
