Distributivity of a segmentation lattice

Discrete Applied Mathematics, 2023
In this interesting paper, finite closure spaces with closed singletons are studied on the level of segmentations, meaning, partitions of the space into closed subsets. These spaces are direct generalizations of topological T1-spaces. The segmentations themselves form a lattice. The authors study such spaces for which this lattice is distributive.

Distributive Projective Lattices

Canadian Journal of Mathematics, 1970
Two basic unsolved problems of lattice theory are (1) the characterization of sublattices of free lattices and (2) the characterization of projective lattices. A solution to an important case of the first problem has been provided by Galvin and Jónsson [3], who characterize distributive sublattices of free lattices.

Monadic Distributive Lattices

Logic Journal of IGPL, 2007
The purpose of this paper is to investigate the variety of algebras, which we call monadic distributive lattices, as a natural generalization of monadic Heyting algebras [16]. It is worth mentioning that the latter is a proper subvariety of the first one, as it is shown in a simple example.

Valuations on Distributive Lattices II

Archiv der Mathematik, 1973
In Parts I and II [Arch. Math. 24, 230–239, 337–345 (1973)] we were principally interested in combinatorial applications of the valuation ring of a distributive lattice. We now show how this ring provides a natural setting for some elementary results in measure theory as well as some classical results on representations of distributive lattices ...

Postulates For Distributive Lattices

Canadian Journal of Mathematics, 1951
Many sets of postulates have been given for distributive lattices and for Boolean algebra. For a description of some of the most interesting and for references to others the reader is referred to Birkhoff's “Lattice Theory”[1].
