Abstract

In this article, we investigate a density problem coming from the linearization of Calder\'on's problem with partial data. More precisely, we prove that the set of products of harmonic functions on a bounded smooth domain Ω\Omega vanishing on any fixed closed proper subset of the boundary are dense in L1(Ω)L^{1}(\Omega) in all dimensions n2n \geq 2. This is proved using ideas coming from the proof of Kashiwara's Watermelon theorem.
