Schrödinger operators and de Branges spaces.
The author gives a new view on the inverse spectral theory of one-dimensional Schrödinger operators by recognizing it as a part of the de Branges theory of Hilbert spaces of entire functions. The de Branges theorem on the connection between a regular de Branges space and canonical systems is considered as the mother of many inverse theorems.
