Hermite–Birkhoff interpolation polynomial of minimum norm in Hilbert space

The Hermite–Birkhoff interpolation problem for a nonlinear operator in the Hilbert space is considered. For this problem, the theorem on the interpolation polynomial of minimum norm generated by a scalar product with a Gaussian measure is proved. Such interpolant is shown to be unique. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.
