Erdős-Hajnal problems for posets

Christian Winter

We say that a poset $(Q, \leq_{Q})$ contains an induced copy of a poset $(P, \leq_{P})$ if there is an injective function $ϕ : P \to Q$ such that for every two $X, Y \in P$ ,\;\;$X\le_P…

Christian Winter

An induced subposet $(P_{2}, \leq_{2})$ of a poset $(P_{1}, \leq_{1})$ is a subset of $P_{1}$ such that for every two $X, Y \in P_{2}$ , $X \leq_{2} Y$ if and only if $X \leq_{1} Y$ . The Boolean lattice $Q_n…
