A characterization of Gabor Riesz bases with separable time-frequency shifts

Christina Frederick, Azita Mayeli

A Gabor system generated by a window function $g \in L^{2} (R^{d})$ and a separable set $Λ \times Γ \subset R^{2 d}$ is the collection of time-frequency shifts of $g$ give…

Finding duality for Riesz bases of exponentials on multi-tiles

Christina Frederick, Kasso Okoudjou

It is known that if $Ω \subset R^{d}$ belongs to a class of multi-tiling domains when translated by a lattice $Λ$ , there exists a Riesz basis of exponentials for $L^{2} (Ω)$ …

Collective motion planning for a group of robots using intermittent diffusion

Christina Frederick, Magnus Egerstedt, Haomin Zhou

In this work we establish a simple yet effective strategy, based on optimal transport theory, for enabling a group of robots to accomplish complex tasks, such as shape formation an…
