Strichartz estimates and local regularity for the elastic wave equation with singular potentials

Seongyeon Kim, Yehyun Kwon, Ihyeok Seo

We obtain weighted $L^{2}$ estimates for the elastic wave equation perturbed by singular potentials including the inverse-square potential. We then deduce the Strichartz estimates un…

Uniqueness in the Calderón problem and bilinear restriction estimates

Seheon Ham, Yehyun Kwon, Sanghyuk Lee

Uniqueness in the Calderón problem in dimension bigger than two was usually studied under the assumption that conductivity has bounded gradient. For conductivities with unbounded g…

Sharp resolvent estimates outside of the uniform boundedness range

Yehyun Kwon, Sanghyuk Lee

In this paper we are concerned with resolvent estimates for the Laplacian $Δ$ in Euclidean spaces. Uniform resolvent estimates for $Δ$ were shown by Kenig, Ruiz and Sogge \cite{KRS…

Carleman estimates and boundedness of associated multiplier operators

Eunhee Jeong, Yehyun Kwon, Sanghyuk Lee

Let $P (D)$ be the Laplacian $Δ,$ or the wave operator $□$ . The following type of Carleman estimate is known to be true on a certain range of $p, q$ : \[ \|e^{v\cdot x}u\|_{L^q(…
