Due to the Knapp phenomenon, the Strichartz estimates on Euclidean spaces for the fractional Laplacian exhibit loss of derivatives. A similar phenomenon appears on real hyperbolic spaces. However, such a loss disappears on homogeneous trees, due to the triviality of the estimates for small times."}],"publication":"Journal of Differential Equations","keyword":["Schrödinger equation","Fractional Laplacian","Dispersive estimates","Strichartz estimates","Real hyperbolic spaces","Homogeneous trees"],"language":[{"iso":"eng"}],"external_id":{"arxiv":["2412.00780"]},"citation":{"apa":"Palmirotta, G., Sire, Y., &#38; Anker, J.-P.
