Nikishin systems on star-like sets: Ratio asymptotics of the associated multiple orthogonal polynomials

Abey López-García, Guillermo López Lagomasino

We investigate the ratio asymptotic behavior of the sequence $(Q_n{)}_{n=0}^{\infty }$ of multiple orthogonal polynomials associated with a Nikishin system of $p\ge 1$ measures tha…
