Abstract

Indefinite inner product spaces of entire functions and functions analytic inside a disk are considered and their completeness studied. Spaces induced by the rotation invariant reproducing kernels in the form of the generalized hypergeometric function are completely characterized. A particular space generated by the modified Bessel function kernel is utilized to derive an analytic continuation formula for functions on R+R^+ using the best approximation theorem of S. Saitoh. As a by-product several new area integrals involving Bessel functions are explicitly evaluated
