Lattices whose congruences form a boolean algebra

1 * Introduction, The structure of a lattice L, in particular its rep-resentation as direct or subdirect unions, depends heavily on the struc-ture of Θ(L), its lattice of congruence relations. Thus a natural problem which arises is that of determining those lattices whose congruence lattices have certain specified properties. Two problems of this general
