Abstract: Let $ L(G)$ be the lattice of all topologies on the group $ G$ which make $ G$ into a topological group. If $ {\tau _1}$ and $ {\tau _2}$ are Hausdorff group topologies and $ {\tau _1} \vee {\tau _2}$ is the discrete topology, then $ {\tau _1} \wedge {\tau _2}$ is a Hausdorff topology. If $ {\tau _1}$ and $ {\tau _2}$ are locally compact Hausdorff group topologies, then $ {\tau _1} \vee {\tau _2}$ is locally compact if and only if $ {\tau _1} \wedge {\tau _2}$ is Hausdorff.
