Abstract

In this paper it is shown that an E-complemented complete modular lattice L with small radical is weakly supplemented if and only if it is semilocal. L is a cofinitely weak supplemented lattice if and only if every maximal element of L has a weak supplement in L. If a/0 is a cofinitely weak supplemented (weakly supplemented) sublattice and 1/a has no maximal element (1/a is weakly supplemented and a has a weak supplement in L), then L is cofinitely weak supplemented (weakly supplemented).
