Title: The quantum group $\dot U$ and flag manifolds over the semifield Z
(Submitted on 6 Sep 2022 (v1), last revised 31 Oct 2023 (this version, v5))
Abstract: We give a parametrization of the canonical basis of the modified quantum group corresponding to a root datum in terms of the flag manifold over the semifield Z associated to the reductive group corresponding to the dual root datum. Some minor errors corrected.
