A Comparison of Certain Representations of Regularly Closed Sets
Peter H. Hertling · Electronic Notes in Theoretical Computer Science · 2002
Ziegler [8] collected and systematically compared many different ways of describing regularly closed subsets of Euclidean spaces. We analyse in more detail the relationship between an especially weak kind of representation of regularly closed sets introduced by Ziegler and other representations. This weak representation allows to make a certain amount of errors in the description.
