Lonely points in $ω^{*}$

Jonathan L. Verner

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 $ω^{*}$ is equivalent to finding a…

Filter convergence in $β ω$

Jonathan L. Verner

We give a necessary combinatorial condition on a filter F to admit an injective F-convergent sequence in $β ω$ . We also show that no analytic filter F admits an injective F-converge…
