Four-Dimensional Non-Reductive Homogeneous Manifolds with Neutral Metrics
A method due to É. Cartan was used to algebraically classify the possible four-dimensional manifolds that allow a (2, 2)-signature metric with a transitive group action which acts by isometries. These manifolds are classified according to the Lie algebra of the group action. There are six possibilit...
