Free Boolean algebras over unions of two well orderings

Given a partially ordered set P there exists the most general Boolean algebra F ˆ ( P ) which contains P as a generating set, called the free Boolean algebra over P. We study free Boolean algebras over posets of the form P = P 0 ∪ P 1 , where P 0 , P 1 are well orderings. We call them nearly ordinal...
