  text: Motivated by the recent introduction of the intrinsic semilattice entropy,
    we study generalized quasi-metric semilattices and their categories. We investigate
    the relationship between these objects and generalized semivaluations, extending
    Nakamura and Schellekens' approach. Finally, we use this correspondence to compare
    the intrinsic semilattice entropy and the semigroup entropy induced in particular
    situations, like sets, torsion abelian groups and vector spaces.

  text: Let X and Y be proper metric spaces. We show that a coarsely n-to-1 map f:X→Y
    induces an n-to-1 map of Higson coronas. This viewpoint turns out to be successful
    in showing that the classical dimension raising theorems hold in large scale;
    that is, if f:X→Y is a coarsely n-to-1 map between proper metric spaces X and
    Y then asdim(Y)≤asdim(X)+n−1. Furthermore we introduce coarsely open coarsely
    n-to-1 maps, which include the natural quotient maps via a finite group action,
    and prove that they preserve the asymptotic dimension.

  text: We generalize Brazas’ topology on the fundamental group to the whole universal
    path space X˜ i.e., to the set of homotopy classes of all based paths. We develop
    basic properties of the new notion and provide a complete comparison of the obtained
    topology with the established topologies, in particular with the Lasso topology
    and the CO topology, i.e., the topology that is induced by the compact-open topology.
    It turns out that the new topology is the finest topology contained in the CO
    topology, for which the action of the fundamental group on the universal path
    space is a continuous group action.
