Superoscillating sequences and supershifts for families of generalized functions

Fabrizio Colombo, Irene Sabadini, Daniele C. Struppa +1

We construct in this paper a large class of superoscillating sequences, more generally of $F$ -supershifts, where $F$ is a family of smooth functions (resp. distri…

Schrödinger evolution of superoscillations with $δ$ - and $δ^{'}$ -potentials

Yakir Aharonov, Jussi Behrndt, Fabrizio Colombo +1

In this paper we study the time persistence of superoscillations as the initial data of the time dependent Schrödinger equation with $δ$ - and $δ^{'}$ -potentials. It is shown that the…
