    Fay's trisecant formula and Hardy \(H^2\) reproducing kernels (English)
    0 references
    Fay's trisecant formula (relating the Riemann theta function and the Klein prime form) was established in (\textit{J. D. Fay}, Theta functions on Riemann surfaces (1973; Zbl 0281.30013) and used to obtain certain identities and inequalities among various conformal invariants. In the paper under review a short proof of this formula is given; next, Fay's formula is applied to some Nevanlinna-Pick type extremal problems.NEWLINENEWLINEFor the entire collection see [Zbl 0957.00034].
