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…

From exact systems to Riesz bases in the Balian-Low theorem

Shahaf Nitzan, Jan-Fredrik Olsen

We look at the time-frequency localisation of generators of lattice Gabor systems. For a generator of a Riesz basis, this localisation is described by the classical Balian-Low theo…
