Congrunce lattices of rectangular lattices

Journal of Intelligent & Fuzzy Systems, 2020
Let D be a finite distributive lattice with n join-irreducible elements. It is well-known that D can be represented as the congruence lattice of a rectangular lattice L ...

Lattices for the lattice Boltzmann method

Physical Review E, 2009
A recently introduced theory of higher-order lattice Boltzmann models [Chikatamarla and Karlin, Phys. Rev. Lett. 97, 190601 (2006)] is elaborated in detail. A general theory of the construction of lattice Boltzmann models as an approximation to the Boltzmann equation is presented.

Lattices That are Embeddable in Suborder Lattices

Algebra and Logic, 2005
Summary: Various types of lattices are embedded in suborder lattices of posets possessing certain properties. In particular, it is shown that the class of lattices isomorphic to sublattices of suborder lattices of posets of length at most \(n\) is a variety, for any \(n < \omega\).

Lattice points in lattice polytopes

Mathematika, 2001
Let \(P\) be a lattice polytope in \(\mathbb{R}^d\) with vertices in \(\mathbb{Z}^d\), and \(I_l(P) = \operatorname{int}(P) \cap l \mathbb{Z}^d\) denote the set of sublattice points of \(P\) in its interior.

On the Lattice of Convex Sublattices of a Lattice

Southeast Asian Bulletin of Mathematics, 2003
In Algebra Univers. 35, 63-71 (1996; Zbl 0842.06003), \textit{S. Lavanya} and \textit{S. Parameshwara Bhatta} considered a partial ordering on the set \(\text{CS}(L)\) of all the convex sublattices of a lattice \(L\), namely \(A\leq B\) if and only if \((A]\subseteq (B]\) and \([A)\supseteq [B)\), and begun a corresponding study.

Lattices of lattice homomorphisms

Algebra Universalis, 1978
IfL andM are lattices, Hom (L, M) denotes the set of homomorphisms ofL intoM with the pointwise partial order.L is calledcatalytic if Hom (L, M) is a lattice for every latticeM. Among other results, it is shown that every retract of a lattice completely freely generated by a partially ordered set is catalytic, and that every catalytic lattice is ...

Congruence Lattices of Finite Lattices as Concept Lattices

1990
In formal concept analysis it is of increasing interest to compute and to represent congruence lattices of finite lattices (for instance, to assist adequate drawings of concept lattices). In this note we give a representation of such congruence lattices as concept lattices which allows the use of developed computer programs to determine and to draw ...
