Conference paper
Part of the Operator Theory: Advances and Applications book series (OT, volume 134)


This paper is a survey of old and recent methods of Krein space operator theory centering around Julia operators, extension problems for contraction operators, Hermitian kernels, and uniqueness questions. Examples related to coefficient problems for univalent functions are briefly discussed.
