Some algebraic and topological properties of subspaces of (pre)orders
arXiv:2010.15681
Abstract
We study algebraic and topological properties of subsets of preorders on a group. In particular we study properties of the composition of two preorders, generalize a topological theorem of \cite{S} in the case of standard orders and show the same theorem in the case of standard preorders. We also show a property of standard valuations.
