Given finite posetsPandQ, we consider a specific idealL(P,Q), whose minimal monomial generators correspond to order-preserving maps. We study algebraic invariants of those ideals. In particular, sharp lower and upper bounds for the Castelnuovo–Mumford regularity and the projective dimension are provided. We obtain precise formulas for a large subclass of these ideals. Moreover, we provide complete characterizations for several algebraic properties ofL(P,Q), including being Buchsbaum, Cohen–Macaulay, Gorenstein, Golod and having a linear resolution.
