Sampling and interpolation in de Branges spaces with doubling phase

Jordi Marzo, Shahaf Nitzan, Jan-Fredrik Olsen

The de Branges spaces of entire functions generalise the classical Paley-Wiener space of square summable bandlimited functions. Specifically, the square norm is computed on the rea…

Modified zeta functions as kernels of integral operators

Jan-Fredrik Olsen

The modified zeta functions $\sum_{n \in K} n^{- s}$ , where $K \subset N$ , converge absolutely for $ℜ s > 1/2$ . These generalise the Riemann zeta function which is known to have…
