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…

Conditional existence of maximizers for the Tomas-Stein inequality for the sphere

Shuanglin Shao, Ming Wang

The Tomas-Stein inequality for a compact subset $Γ$ of the sphere $S^{d}$ states that the mapping $f \mapsto f σ$ is bounded from $L^{2} (Γ, σ)$ to $L^{2 + 4/ d} (R^{d + 1})$ . Then co…

Quantitative observability for the Schrödinger equation with an anharmonic oscillator

Shanlin Huang, Gengsheng Wang, Ming Wang

This paper studies the observability inequalities for the Schrödinger equation associated with an anharmonic oscillator $H=-\frac{\d^2}{\d x^2}+|x|$. We build up the observability…

Observability inequality, log-type Hausdorff content and heat equations

Shanlin Huang, Gengsheng Wang, Ming Wang

This paper studies observability inequalities for heat equations on both bounded domains and the whole space $R^{d}$ . The observation sets are measured by log-type Hausdorff…

Observability of dispersive equations from line segments on the torus

Yunlei Wang, Ming Wang

We investigate the observability of a general class of linear dispersive equations on the torus $T$ . We take one line segment or two line segments in space-time region as…
