For any finite posetP, we have the poset of isotone maps, also called-partitions. To any poset idealin, finite or infinite, we associate monomial ideals: the letterplace idealand the Alexander dual co-letterplace ideal, and study them. We derive a class of monomial ideals incalledP-stable. WhenPis a chain, we establish a duality on strongly stable ideals. We study the case whenis a principal poset ideal. WhenPis a chain, we construct a new class of determinantal ideals which generalizes ideals ofmaximalminors and whose initial ideals are letterplace ideals of principal poset ideals.
