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…
Segre Types of Symmetric Two-tensors in n-Dimensional Spacetimes
J. Santos, M. J. Reboucas, A. F. F. Teixeira
Three propositions about Jordan matrices are proved and applied to algebraically classify the Ricci tensor in n-dimensional Kaluza-Klein-type spacetimes. We show that the possible…
Classification of Second Order Symmetric Tensors in 5-Dimensional Kaluza-Klein-Type Theories
J. Santos, M. J. Reboucas, A. F. F. Teixeira
An algebraic classification of second order symmetric tensors in 5-dimensional Kaluza-Klein-type Lorentzian spaces is presented by using Jordan matrices. We show that the possible…
