Topology and nematic ordering

Physical Review Letters, 1993
We consider the weakly first-order phase transition between the isotropic and ordered phases of nematics in terms of the behavior of topological line defects. Specifically, we present analytical and Monte Carlo results for a new coarse-grained theory of nematics which incorporates the inversion symmetry of nematics as a local gauge invariance ...

Topologies on products of partially ordered sets III: Order convergence and order topology

Algebra Universalis, 1981
This paper deals with the question under which circumstances filter-theoretical order convergence in a product of posets may be computed componentwise, and the same problem is treated for convergence in the order topology (which may differ from order convergence). The main results are:

Order Environments of Topological Spaces

Acta Mathematica Sinica, English Series, 2004
An order environment of a~space~\(X\) is a~continuous poset~\(D\) such that \(X\) is homeomorphic to the space \(\text{Max}(D)\) of maximal points of~\(D\) with topology inherited from the Scott topology of~\(D\) and such that the Scott topology agree with Lawson topology at \(\text{Max}(D)\). During recent years some classes of spaces (locally compact

Order-convexity in order topologies

Optimization, 2000
In this survey the role of order-convexity in topologies compatible with a preference (i.e a negatively transitive partial order) is considered.
