Lonely points in $\omega^*$

General Topology 2016-07-22 v1

Abstract

Inspired by the work of J. van Mill we define a new topological type --- lonely points. We show that the question of whether these points exist in ω\omega^* is equivalent to finding a countable OHI, extremally disconnected, zerodimensional space with a remote weak P-point. We also present methods which allow us to find lonely points in a large subspace of ω\omega^* and show why known methods do not allow us to construct them in all of ω\omega^*.
