The trisecant identity and operator theory
The author's summary: ``For the special case of a Riemann surface which arises as the double of a planar domain \(R\), the trisecant identity has a natural interpretation as a relation among reproducing kernels for subspaces of the Hardy space \(H^2(R)\). This relation and Riemann's theorem on the vanishing of the theta function is applied to Nevanlinna-Pick interpolation on \(R\)''.
