Abstract:
We study modules that are lattice isomorphic to linearly compact modules (in the discrete topology). In particular, we establish the equivalence of the following properties of a module $M$: 1) $M$ satisfies the Grothendieck property \textrm{AB$5^*$} and all its submodules are Goldie finite-dimensional; 2) $M$ is lattice isomorphic to a linearly compact module; 3) $M$ is lattice antiisomorphic to a linearly compact module. We show that a linearly compact module cannot be determined in terms of the lattice of its submodules.
