An action of a topological group G on a topological space X is orbit nonproper if, for some cursive Greek chi ∈ X, the map g → gcursive Greek chi : G → X is nonproper. We describe the collection of connected, simply connected Lie groups admitting a locally faithful, orbit nonproper action by isometries of a connected Lorentz manifold.
