Abstract

We establish quantum dynamical upper bounds for quasi-periodic Schr\"odinger operators with Liouville frequencies. Our approach combines semi-algebraic discrepancy estimates for the Kronecker sequence {nα}\{n\alpha\} with quantitative Green's function estimates adapted to the Liouville setting.
