Homogenousness and Specificity

CoRR, 2019
We interpret homogenousness as a second order property and base it on the same principle as nonmonotonic logic: there might be a small set of exceptions. We use this idea to analyse fundamental questions about defeasible inheritance systems. In an appendix, we discuss the concept of the core of a (model) set.

Homogeneity properties with isometries and Lipschitz functions

, 2010
We consider metric variants of homogeneity, countable dense homogeneity (CDH) and strong local homogeneity (SLH) by requiring that the homeomorphisms that witness the homogeneity be isometries, respectively bi-Lipschitz maps that are almost isometries ...
