Abstract
We construct the Schwartz kernel of resolvent and spectral measure for Schrödinger operators on the flat Euclidean cone (X,g), where X=C(Sσ1)=(0,∞)×Sσ1 is a product cone over the circle, Sσ1=R/2πσZ, with radius σ>0 and the metric g=dr2+r2dθ2. As products, we prove the dispersive estimates for the Schrödinger and half-wave propagators in this setting.
