Bulletin of the Section of Logic, 2018 In this paper we study pseudo-BCH algebras which are semilattices or lattices with respect to the natural relations ≤; we call them pseudo-BCH join-semilattices, pseudo-BCH meet-semilattices and pseudo-BCH lattices, respectively. We prove that the class of all pseudo-BCH join-semilattices is a variety and show that it is weakly regular, arithmetical at

Simplicial homology and hochschild cohomology of banach semilattice algebras [PDF]
The ℓl1-convolution algebra of a semilattice is known to have trivial cohomology in degrees 1, 2 and 3 whenever the coefficient bimodule is symmetric. We extend this result to all cohomology groups of degree ≥ 1 with symmetric coefficients.

Countable chains of distributive lattices as maximal semilattice quotients of positive cones of dimension groups [PDF]
, 2006 summary:We construct a countable chain of Boolean semilattices, with all inclusion maps preserving the join and the bounds, whose union cannot be represented as the maximal semilattice quotient of the positive cone of any dimension group.

A city is not a semilattice either [PDF]
In 1965 Christopher Alexander took the original step of analysing the city in graph theoretical terms and concluded that its historical or natural form is a semilattice and that urban planners of the future should adhere to this model.

On the congruence lattice of a semilattice [PDF]
, 1975 Here is attempted an examination of three aspects of the lattice [theta](S) of congruence relations of a semilattice S (usually a join semilattice).

Biflatness of $\ell^1$-semilattice algebras [PDF]
, 2007 We show that if L is a semilattice then the l1-convolution algebra of L is biflat precisely when L is "uniformly locally finite". Our proof technique shows in passing that if this convolution algebra is biflat then it is isomorphic as a Banach algebra to

Biflatness of l1-semilattice algebras [PDF]
We show that if L is a semilattice then the l1-convolution algebra of L is biflat precisely when L is "uniformly locally finite". Our proof technique shows in passing that if this convolution algebra is biflat then it is isomorphic as a Banach algebra to
