Global Phase Portrait and Large Degree Asymptotics for the Kissing Polynomials

Ahmad Barhoumi, Andrew F. Celsus, Alfredo Deaño

We study a family of monic orthogonal polynomials which are orthogonal with respect to the varying, complex valued weight function, $exp (n sz)$ , over the interval $[- 1, 1]$ , where $…

Supercritical Regime for the Kissing Polynomials

Andrew F. Celsus, Guilherme L. F. Silva

We study a family of polynomials which are orthogonal with respect to the varying, highly oscillatory complex weight function $e^{niλ z}$ on $[- 1, 1]$ , where $λ$ is a positive parame…
