Roughness in Orthomodular Lattices

open access: yesInternational Journal of Mathematics and Soft Computing, 2012
In this paper, we define the rough approximation operators in an algebra using its congruence relations and study some of their properties. Further, we consider the rough approximation operators in orthomodular lattices. We introduce the notion of rough ideal (filter) with respect to a p-ideal in an orthomodular lattice.

The near center of an orthomodular lattice [PDF]

open access: yesJournal of the Australian Mathematical Society, 1972
The results described herein were obtained in connection with the development of some lattice theoretic machinery needed by Randall and Foulis in their treatment of the so-called “logic of empirical science” (See [3] for an introduction to this subject).
