Charles Sanders Peirce, with characteristic insight, had stated the fundamental dilemma of the pure scientist operating within a democratic framework. How can one ask the public to provide support, much less facilities,

Pure ℓ-Ideals in Lattice-Ordered Rings#
Communications in Algebra, 2005An l-ideal I of a commutative lattice-ordered ring R with positive identity element is called a pure l-ideal if R = I + l( x ) for each x ∈ I , where l(x) is the l-annihilator of x in R . In this article, we give some results on pure l-ideals and study the l-ideal structure of a commutative lattice-ordered ring with positive identity element by ...
