The strongly Leibniz property and the Gromov-Hausdorff propinquity

We construct a new version of the dual Gromov-Hausdorff propinquity that is sensitive to the strongly Leibniz property. In particular, this new distance is complete on the class of strongly Leibniz quantum compact metric spaces. Then, given an inductive limit of C*-algebras for which each C*-algebra the inductive limit is equipped with a strongly Leibniz L-seminorm, we provide sufficient conditions for placing a strongly Leibniz L-seminorm on an inductive limit such that the inductive sequence converges to the inductive limit in this new Gromov-Hausdorff propinquity. As an application, we place new strongly Leibniz L-seminorms on AF-algebras using Frobenius-Rieffel norms, for which we have convergence of the Effros-Shen algebras in the Gromov-Hausdorff propinquity with respect to their irrational parameter.& COPY; 2023 Elsevier Inc.
