Chains and antichains in Boolean algebras

M. Losada, Stevo Todorčević (2000)

Fundamenta Mathematicae

We give an affirmative answer to problem DJ from Fremlin’s list [8] which asks whether $M A_{ω_{1}}$ implies that every uncountable Boolean algebra has an uncountable set of pairwise incomparable elements.

Characterization of posets of intervals

Judita Lihová (2000)

Archivum Mathematicum

If $A$ is a class of partially ordered sets, let $P (A)$ denote the system of all posets which are isomorphic to the system of all intervals of $A$ for some $A \in A .$ We give an algebraic characterization of elements of $P (A)$ for $A$ being the class of all bounded posets and the class of all posets $A$ satisfying the condition that for each $a \in A$ there exist a minimal element $u$ and a maximal element $v$ with $u \leq a \leq v,$ respectively.

Characterizations of 0-distributive posets

Vinayak V. Joshi, B. N. Waphare (2005)

Mathematica Bohemica

The concept of a 0-distributive poset is introduced. It is shown that a section semicomplemented poset is distributive if and only if it is 0-distributive. It is also proved that every pseudocomplemented poset is 0-distributive. Further, 0-distributive posets are characterized in terms of their ideal lattices.
