On L1-norms for non-harmonic trigonometric polynomials with sparse frequencies

Philippe Jaming, Karim Kellay, Chadi Saba +1

In this paper we show that, if an increasing sequence $Λ = (λ_{k})_{k \in Z}$ has gaps going to infinity $λ_{k + 1} - λ_{k} \to + \infty$ when $k \to \pm \infty$ , then for every $T > 0$ and…

Quantitative 2D propagation of smallness and control for 1D heat equations with power growth potentials

Yunlei Wang

We study the relation between propagation of smallness in the plane and control for heat equations. The former has been proved by Zhu who showed how the value of solutions in some…
