....[7, 10, 13, 46] Here we show that the set f(XR ; X R ) j X Ug, where R 2 Tol(U) is not necessarily even a semilattice with respect to the coordinatewise order if jU j 5. 7 Chapter 2 Preliminaries All general lattice theoretical and algebraic notions used in this work can be found in [1, 2, 3, 4, 5, 15, 16], for example. 2.1 General Notation and Conventions Sets. We assume that the reader is familiar with the following notations: membership (2) set builder (f Gamma j Gammag) subset ( proper subset (ae) union ( intersection ( difference ( Gamma) complement ( ordered n tuples ....

.... (A(E) can be embedded into ( U) A lattice L = L; is distributive if it satisfies (D1) x (y z) x y) x z) or (D2) x (y z) x y) x z) for all x; y; z 2 L; it is well known that if a lattice satisfies one of the identities (D1) and (D2) it satisfies both of them (cf. [15], for example) Suppose that L has a zero 0. An element x is a pseudocomplement of x 2 L, if x x = 0 and for all a 2 L, x a = 0 implies a x . An element can have at most one pseudocomplement. A lattice is pseudocomplemented if each element has a pseudocomplement. A bounded ....
