Controllable subspaces and real-part observability for Schrödinger equations on $T^{d}$

Gengsheng Wang, Ming Wang

We study internal controllability of Schrödinger equations on tori with controls acting only through their real parts. This real-part constraint leads to a real-linear control prob…

Curved Ingham Inequalities for Dispersive Trigonometric Sums

Bernhard H Haak, Philippe Jaming, Ming Wang +1

We study $L^{2}$ restrictions of dispersive trigonometric sums $F (t, x) = n \in Z \sum c_{n} e^{2 π i (∣ n ∣^{s} t + n x)}$ to curves in the $(t, x)$ -plane. Our main result is a curved analogue…
