Introduction to Topological Spaces and Set-Valued Maps
... Definition 2.2.10 (boundary). Let A ⊂ X be non-empty. Then boundary ∂A of A is defined as ∂A := clA \ intA. Note that, if A is a closed set, then ∂A ⊂ A. Definition 2.2.11 (dense set). A subset D of a metric space < X, ρ > is dense in X iff clD = X. That is, a set is dense if its closure is the who ...

Partial Metric Spaces - Department of Computer Science
... 5. EQUIVALENTS FOR PARTIAL METRIC SPACES. Partial metric spaces arose from the need to develop a version of the contraction fixed point theorem which would work for partially computed sequences as well as totally computed ones. Since then much research has been aimed at extrapolating away from compu ...

A note on reordering ordered topological spaces and the existence

These are the questions that we will answer in Section II. Wellman’s original question involved the reorde ...
