Lower bounds of sets of P-points

Borisa Kuzeljevic, Dilip Raghavan, Jonathan L. Verner

We show that $MA_{κ}$ implies that each collection of $P_{c}$ -points of size at most $κ$ which has a $P_{c}$ -point as an $R K$ upper bound also has a ${…

Cofinal types on $ω_{2}$

Borisa Kuzeljevic, Stevo Todorcevic

In this paper we start the analysis of the class $D_{ℵ_{2}}$ , the class of cofinal types of directed sets of cofinality at most $ℵ_{2}$ . We compare elements of $\mat…

Antichains of Copies of Ultrahomogeneous Structures

Miloš S. Kurilić, Boriša Kuzeljević

We investigate possible cardinalities of maximal antichains in the poset of copies $⟨ P (X), \subset ⟩$ of a countable ultrahomogeneous relational structu…
