A measure- $L^{\infty}$ div-curl lemma

Valeria Banica, Nicolas Burq

In this note we give a very short proof of the div-curl lemma in the limit conjugate case $M - L^{\infty}$ , where $M$ is the set of Radon measures on $R^{d}$ .…

Delocalized eigenvectors of transitive graphs and beyond

Nicolas Burq, Cyril Letrouit

We prove delocalization of eigenvectors of vertex-transitive graphs via elementary estimates of the spectral projector. We recover in this way known results which were formerly pro…

Strichartz Estimates for a Class of Baouendi-Grushin Operators

Nicolas Burq, MickaÃ«l Latocca

We prove Strichartz estimates for a class of Baouendi--Grushin operators acting either on the Euclidean space or a product of the type $R^{d_{1}} \times M$ , where $(M, g)$ is…
