Holonomy groups and spacetimes
G. S. Hall, D. P. Lonie
A study is made of the possible holonomy group types of a space-time for which the energy-momentum tensor corresponds to a null or non-null electromagnetic field, a perfect fluid o…

On the Algebraic Structure of Second Order Symmetric Tensors in 5-Dimensional Space-times
G. S. Hall, M. J. Reboucas, J. Santos +1
A new approach to the algebraic classification of second order symmetric tensors in 5-dimensional space-times is presented. The possible Segre types for a symmetric two-tensor are…
