  text: We investigate dispersive and Strichartz estimates for the Schrödinger equation
    involving the fractional Laplacian in real hyperbolic spaces and their discrete
    analogues, homogeneous trees. 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.
