Boundary interpolation for slice hyperholomorphic Schur functions

K. Abu-Ghanem, D. Alpay, F. Colombo +2

A boundary Nevanlinna-Pick interpolation problem is posed and solved in the quaternionic setting. Given nonnegative real numbers ${\kappa }_1,\dots ,{\kappa }_N$, quaternions $p_1,\dots ,p_N$…
