Free $Q$-distributive lattice over an $n$-element chain
L Monteiro, Manuel F. Abad, Marta A. Zander · Americanae (AECID Library) · 2004
In this note we provide an explicit construction of $FQ({\\bf n})$, the free $Q$-distributive lattice over an $n$-element chain, different from those given by Cignoli [4] and Abad--Díaz Varela [1], and prove that $FQ({\\bf n})$ can be endowed with a structure of a De Morgan algebra.
