Formal Reproducing Kernel Hilbert Spaces
Joseph A. Ball, Vladimir Bolotnikov · Cambridge University Press eBooks · 2021
Chapter 2 develops the basic notion of Formal Noncommutative Reproducing-Kernel Hilbert Space which generalizes the classical notion of Reproducing Kernel Hilbert Space to a noncommutative setting. This formalism in turn is a convenient formalism for modeling freely noncommutative shift-operator tuples.
