On the Concept of a Screen.
Abstract
In a former paper one has defined the concept of a screen. The basic set in this definition was assumed to be an ordered set. In most applications, however, the basic set is not only an ordered set but a complete lattice. Under this assumption one shows in this paper that the concept of a screen is equivalent to the concept of a certain sublattice. Using this relation further necessary and sufficient conditons for a screen can be derived from lattice theory. Similar relations hold a lower and upper screen. (Author)
