Riemann-Hilbert problem associated with Angelesco systems

By A. Branquinho, U. Fidalgo Prieto and A. Foulquié Moreno

Abstract

Angelesco systems of measures with Jacobi type weights are considered. For such systems, strong asymptotic development expressions for sequences of associated Hermite-Pad´e approximants are found. In the procedure, an approach from Riemann-Hilbert Problem plays a fundamental role.CMUC; FCT SFRH/BPD/31724/2006; UI Matemática e Aplicações from University of Aveir
