Nonlinear determination and phase retrieval under unimodular constraints
Lukas Liehr, Tomasz Szczepanski
We study nonlinear determination problems in Hilbert spaces in which inner products are observed up to prescribed rotations in the complex plane. Given a Hilbert space and a su…

Translation-based completeness on compact intervals
Lukas Liehr
Given a compact interval , and a function that is a product of a nonzero polynomial with a Gaussian, it will be shown that the translates $\{ f(\cdot -…
