OCA and towers in
We shall show that Open Coloring Axiom has different influence on the algebra than on . The tool used to accomplish this is forcing with a Suslin tree.

On a property of partially ordered sets.
On A System Of All Maximal Chains (Antichains) Of A Graph
On a Theory of Scale Types.

On an axiom concerning the theory of “interval orders”.
On an integer sequence related to a product of trigonometric functions, and its combinatorial relevance.
On automorphism groups of cyclically ordered sets.

On CCC boolean algebras and partial orders
We partially strengthen a result of Shelah from [Sh] by proving that if and is a CCC partial order with e.g. (the successor of ) and then is -linked.
On chains and posets within the power set of a continuum.
On chains whose power semigroups are lattices.
