Any nonvoid lattice of subspaces from R" is known to be a complete lattice, and hence it has a largest and smallest element. Here we show that for a specific class of subspaces also the converse is true. If this class has a largest and a smallest element, then it is a complete lattice. Within the co
## A NOTE ON REAL SUBSETS OF A RECURSIVELY SATURATED MODEL by ATHANASSIOS TZOWARAS in Thessaloniki (Greece) 9 0. Introduction Let L = [+, ., I , <, 0} be the language of Peano Arithmetic (PA) and let M be a countable recursively saturated model of PA. For every a E M let -a be the equivalence x -a
