- Mathematics
- 22 December 2010
In this article we have successfully obtained an exact solution of a particular case of SIR and SIS epidemic models given by Kermack and Mckendrick [1] for constant population, which are described by…

Lie symmetries of the Ricci and energy-momentum tensors
- H. Khan, A. Qadir, K. Saifullah, M. Ziad
- Mathematics, Physics
- 27 November 2013
Abstract.Though the Ricci and energy-momentum tensors have the same algebraic symmetries and appear in a similar way in the Einstein equations, in that interchanging them and inverting the…
A NOTE ON CLASSIFICATION OF TELEPARALLEL CONFORMAL VECTOR FIELDS IN BIANCHI TYPE I SPACE-TIMES IN THE TELEPARALLEL THEORY OF GRAVITATION
- G. Shabbir, H. Khan, Received July
- Physics, Mathematics
- 2014
A study of teleparallel conformal vector fields in Bianchi type I space-times in the teleparallel theory of gravitation is given by using the direct integration technique. From the above study it…
Do the Ricci and energy-momentum tensors have
- H. Khan, A. Qadir, K. Saifullah, M. Ziad
- Mathematics
- 23 November 2010
The Ricci and energy-momentum tensors have the same algebraic symmetries. In the Einstein equations they look ``dual'' to each other, in that interchanging them and inverting the gravitational…
