Unique continuation at infinity: Carleman estimates on general warped cylinders

Nicolò De Ponti, Stefano Pigola, Giona Veronelli

We obtain a vanishing result for solutions of the inequality $|\hat{I}”u|\le q_1|u|+q_2|\nabla u|$ that decay to zero along a very general warped cylindrical end of a Riemannian manifold…
