Resumen de Pseudo H-type 2-step Nilpotent Lie Groups

Keun Park, Changrim Jang, Phillip E. Parker

• Pseudo H-type is a natural generalization of H-type to geometries with indefinite metric tensors. We give a complete determination of the conjugate locus including multiplicities. We also obtain a partial characterization in terms of the abundance of totally geodesic, 3-dimensional submanifolds
